Oozy's Restroom Trip

Alright, listen up, buttercup. This joke is playing on the word "oozy." It sounds like "use zi" which sounds like "use the" and the person wants to "use the toilet." It's funny 'cause it makes no damn sense! You wouldn't go to the toilet to eat trains, you dum-dum. By the way, I bet you still wipe sitting down. Disgusting.
