Corrected entry: When Patchy is pointing to the cave drawings at the beginning, his hook hand is gone.
Corrected entry: When Patchy is being "eaten" by the t-rex, you can tell he is lying down flat on his back on a green screen floor, and the t-rex is just a puppet held next to him.
Correction: Yes, we can all tell that it's a puppet, which is why it was deliberately drawn that way for the humor. So where's the mistake?
Correction: While that may be true, that's one of the running gags throughout Patchy's skits. His peg leg, hook, and patch all change places on his body from left side to right side. In other episodes, the hook or patch or leg do disappear altogether. That's the gag.
