An hour ago I found out my dog has an extra leg three inches below its right rib. One of them, anyway. It's not a very big leg, it's retractable, so you don't notice until my dog is either bored or wants to scare the shit out of you.
I decided to play a prank on my mom, so I told her to come to the kitchen, that I needed her help. I grabbed some milk and poored it in a glass and screamed "OPERATION: ZUCINI: GO!" and my dog stood on its hind legs and punched my mom in the stomach with her extra leg. I thought it was hilarious. My mom got a stomach ulcer and now she's in the hospital.
You'd think I feel guilty, but I don't, because it was just too goddamn funny. The look on her face was priceless.
