Hahahaha. I used to do stuff like this to my cat. If you take masking tape and put your hand on it a few times, it loses most of its tackiness, and you can safely attach it to things like skin or cats without fear of removing any sort of hair.
Another hilarious thing is to put a piece of tape on each foot of a cat, they walk around like they're drunk, their legs go waaay up in the air, sometimes they just can't deal and fall over.
You can also get a cat to chase its tail if there's tape on it

haha, memories.
