Whats your favorite bad joke?

I love to make really bad similes/metaphors like "I have the memory of a fish with very poor memory" or "I'm as tall as a tree thats my height".

I’m still found of the classic “Why is six afraid of seven? Because seven ate nine!” Those kids going on about 6-7 like it’s some kind of power couple don’t know what they’re doing to poor 6.
Do you know why 7 8 9? Because you’re supposed to get three square meals a day.
