Couple of guys I worked with were deathly afraid of snakes. I bought some rubber ones and got all the rest of the shop involved. We'd leave them all over the place waiting for the guys to find them. We always knew when they did find them, they could be heard screaming in the next county over.
After awhile they didn't get bothered by them anymore and actually took a couple of them and used them with people they knew who were scared of snakes. They had more fun than I did.
Two things are infinite: the universe and human stupidity; and Im not sure about the universe. Albert Einstein
