T.R Knight's George O'Malley will always be an unforgettable part of Grey's Anatomy, both for his shameless and decent, compassionate actions.

Actor T.R Knight's George O'Malley will probably remain etched into the memories of Grey's Anatomy fans forever. One of the most gentle, compassionate male characters ever written forpopular television, George was an instant fan-favorite and the fact that his character died such a devastatingdeath made him all the more memorable.

One of the original interns at Seattle Grace Hospital, George was beloved in almost every way possible but there were twists in his character that messed with his arc at times. There were very few things the kind and empathetic George did that can be considered shameless but here are some that can come close, and a few others that would make any man proud.

George was one of the only people at Seattle Grace aware of Burkes tremor after his shooting and the fact that he and Cristina were keeping it a secret. Now,George was completely justified in his discomfort sinceBurke and Cristins little team effort where they continued to perform surgeries even though Burke wasnt ready, was completely unethical.

The duo was even ready to operate of George's own father. But perhaps he took it a little too far when he stopped talking to Cristina even though no damage had really been done. After all, Cristina was already under a lot of stress fromshielding Burke.

When Joe, everybody's favorite bartender, collapsed inside his own bar, the doctors at the hospital naturally did their best to save their go-to guy who was privy to so many of their little secrets.

However, Joe refused the brain surgery he needed due to the insurmountable expense it would involve, which might, in turn, cause him to lose his bar. It was George who took it upon himself to convince Richard Webber to fund the cost of the surgery by getting Joe into a grant with a research foundation. The effort George took to save Joe and help him keep his beloved bar was indeed commendable.

George himself might not have even realized it, but he seemed to be using Callie as a kind of rebound and a way to make himself feel better after his unfortunate incident with Meredith.George had, as fans would recall, always harbored an enormous crush on Meredith.

But unfortunately, the latter, who was going through a phase at the time, had started crying when she was in bed with himwhich was totally unfair. George's affair with Callie started soon after and although it was Callie who took the initiative, George's whole storyline with her felt forced, and somewhat like a rebound.

George came from a family where becoming a surgeon was almost unimaginable. He was intellectually much more advanced than most other members of his family, especially his two brothers who teased him relentlessly when they realized he wasn't yet a proper doctor and only an intern.

George, however, didn't let his family tie him down or pull him back. He became a surgical intern and then a resident and would surely have gone on to be a successful surgeon in time.

George and Alex started fighting in the episode "Where The Boys Are" becauseAlex had just told George that Callie had been unfaithful to him with Mark Sloan. Interestingly enough, Alex was actually telling the truth, and the slap-fight led to Walter,the bartender Joe's boyfriend, hitting his head against a rock.

Even though the whole thing was an accident, George was left feeling guilty. Although it is hard to necessarily call this shameless, he could surely have been more mature and responsible.

George performed an extraordinary feat when he operated on a young patient who needed heart surgery inside an elevator that had got stuck due to a power shortage.

George was only an intern at the time and not ready to take on such a daunting task on his own. However, while Alex froze, it was George who stepped up and took charge, thoroughly impressing Preston Burke. Under Burke's instructions, he went on to perform the surgery inside the elevator, saving his patient's life almost single-handedly.

Young Lexie Grey had a crush on George when she first arrived at Seattle Grace. She was extremely sweet to George, which was typical of her gentle nature. She even tried to protect himfrom getting hurt by keeping the fact that he was repeating a year as an intern from her fellow-interns.

However, George never seemed to notice her rather obvious feelings, even though the two shared a dilapidated apartment for a while. George and Lexie would have made an ideal couple, but the former ended up hurting Lexie when he failed to pay her any attention. This wasn't exactly shameless but really, however, Lexie did end up getting hurt.

George O'Malley was inspired by Owen Hunt who had just joined the hospital after a tour of Iraq to become a trauma surgeon. Owen had told George that despite his passiveways, hehad the potential to become an excellent trauma surgeon.

For soft, gentle George to enlist in the army would have taken unbelievable courage and motivation to help people. Of course, George never ended up actually joining the military as a surgeon but this was something he should have been incredibly proud of.

One of the worst things George did and possibly thetrulyshameless one was his affair with Izzie while still being married to Callie Torres. Callie and George were not the best fit and they got married too early. However, George cheating on Callie who had been nothing but good, caring, and loving to him, made no sense at all.

The Callie-George-Izzie triangle was one of the worst storylines in the series, receiving quite a bit of flak from fans, and sending George's character completely haywire. It was thoroughly uncharacteristic of himto stoop to this level and definitely rather shameless.

While his cheating on Callie wasn't his proudest moment, George did something else that would quite literally become the most selfless thing he ever did. He threwhimself in front of a bus to save a random stranger on the street.

Fans remember the season 5 finale as one of the most shocking and tragic season finales in the history of the series as George O'Malley was admitted to Seattle Grace as a John Doe after getting hit by a bus to save a woman he didn't even know. His face was so badly disfigured that his own friends were unable to recognize him. George died painfully, practically giving his life for a stranger, which was the ultimate sacrifice and the proudest thing one can do.
