I got into one of these contests years ago with a co-worker. Nothing seemd to phase him, I mean nasty, gros, make you wan to hurl type stuff - absolutely nothing. I went to the cafeteria in the building as usual one afternoon and the counter guy was pulling out fresh hot chocolate chip cookies. I got three in a bag and headed back to the office. This guys office was on the way to mine and I was eating one of the cookies. He asked what I had and I offered him a cookie, which he took. After he had a bite, I said "yeah, these looked pertty good, they just came out of the oven and were making some more. Didn't know it took three people to make these." He looke at me and said "three?". I said "three, two to roll out the cookie and one to squeeze the rabbit." I then wiped my finger across one of the warm chocolate chips which rubbed off on my finger, showed it to him and said "See". Expression on his face was priceless.
I think I won, since he never tried to gross me out again.
