Practical joke
Feed the monkey
I usually hate practical jokes. They're a cheap way of performing some action, getting another person's reaction, retracting your original action and leaving them high and dry unable to retract theirs. I'd use stronger words if I didn't think you got how I really felt. Let's assume you do. The practical joke in the video below is actually funny. The only think it reveals about the victims is that they're not so wealthy that it's not worth their time to get a little extra change and I think that only paints them in a positive light. It's a practical joke but instead of possibly showing people in a negative light it flatters them. It's 5 minutes long thought so feel free to fast forward. Ironically, I know some of you who are reading this have been caught on a similar stunt.
