We put a chub in my buddies beer. He had some clear bottle kind so he could see it. He drank the beer pretending he didn't notice. When he got to the bottom he holds the chub up, goes "watch this aholes", and eats the frickin chub.
Years ago, my wife was getting a piece of pizza and when she grabbed the little leftover cheese, an onion flew off of it, through the air and right into my bottle of Pepsi. That Pepsi was almost undrinkable it tasted so bad.
