What's the best prank you ever did or seen?
The other day, there was a customer at my job with a bag of googly eyes and glue in his hand and he was putting them on the mannequins. I kind of saw him doing it at the corner of my eye, but I ignored it because I thought it was funny and clothing isn't my department(Market is). Now the store's faceless, colorless, mannequins, have tiny googly eyes on them. It's creeping out the customers and my coworkers find it kind of fun watching it.
How about you guys? Best prank you ever did, seen, or heard of?
