Someone stole my toilet, and the police have nothing to go on.
Stolen Toilet
Explanation

Alright, listen up, you chucklehead. You clearly don't get it. This ain't rocket science, you know. It's called a pun, which is a form of wordplay. The joke uses the phrase "nothing to go on" in a dual sense, implying both a lack of evidence and also the literal absence of the toilet. Because people use the toilet to go to the bathroom, get it now?
