In 1999, the world met Aibo, the $2,500 robotic dog from Sony. The following year brought quite the litter of less expensive mechanized pups. Real dogs, however, had mixed feelings about their cyber counterparts.

There was the immobile singing Poo-chi by Tiger Electronics, a company that also made the i-Cybie, which could lift its leg and roll over. The $99 Fisher-Price Rocket the Wonder Dog, which was operated via infrared headset, could burp and scratch itself. There was also Tekno by Manley Toy Quest, Big Scratch and Lil' Scratch by Trendmasters, Puppy Magic by Toy Biz and more.

Many people who had both real dogs and fake dogs decided to see what would happen when the two worlds collided.

If I had a fake dog... you know, the idea seems so preposterous to me that I can't even go there. My real dog is looking at me as I sit here on my shiny computer which is flanked by my shiny iPod and phone. "Aren't you glad I don't require electricity to operate?" he is saying with his eyes. "Don't you want to take me to the park and escape the backlit cyber world you are immersed in so many hours a day?" Why yes, Amos, I do. Now stop dragging your butt.

If these cyber versions were meant to appeal to real wannabe dog owners, I think they should've made them look a little more doglike. Would it have been so hard to slap some fake fur on these things? I'm thinking they could've gone with some Muppet fur—shaggy blue, maybe. Or Elmo red. Who wants a pet that looks like Robocop. Also: my real dog earns his keep by licking clean the dinner plates and jumping in the laps of cute guys at the park. The cyber curs had no such uses. If I'm going to shell out that kind of money for a non-breathing pet, I'd at least like if it could second as a vacuum.

Nevertheless, many robotic dog owners thought it'd be very original and clever and hilarious to introduce their real pet to their fake pet, as evidenced by the following videos...

German Shepherd doesn't let Aibo touch its meat

Sparky gets in some hot two-on-one action with a Doberman and a Chihuahua

Dog asks the Poo-Chi why it isn't wearing any clothes

A cat watches an impertinent iCybie take a pee

This particular school of cinema reached its nadir with robo-dog snuff films
