Reminds me of a Canadian one-off cartoon. A scientist was showing off his new invention, a teleporter. In one booth, turn on, appear in other booth. Someone asks him to open the doors so they can make sure he isn’t just using a tunnel. Annoyed, he agrees. Steps into booth, turns it on, gets crushed to death by a hydraulic press and is recreated in the second booth. Bystander asks what happens if you turn off the press. Scientist agrees, starts up the machine. Now there’s a bunch of scientist clones. They all play chess until one winner is found (he cheats, by the way). All the other clones have to kill themselves. The end!
Oh Canada, you so crazy.
