Cheeky Question

Alright listen up, smoothbrain. This "joke" is all about the butt. One butt cheek asks the other about a nasty smell. It's funny 'cause butts are stinky, and the cheek used British slang "Blimey". It is also funny because the cheek is asking the other cheek where the smell is coming from when they both should know. You probably don't know what "blimey" means, huh? You are probably the person who farts and blames it on someone else, aren't you?
