Want to gross out a friend who absolutely hates dogs? Then get him or her the Happy Birthday Dog Poop, and chances are the both of you will be friends no more in an instant. It looks extremely realistic, and if you want to up the ante, why not spray some stink scent on it before presenting it as a gift? The fake dog poo has been designed to spell out Happy Birthday, and is made out of realistic rubber. One of the crazier $12.95 you’ll ever spend, that’s for sure.
