So a man walks into a bar with a crocodile on a leash
The bartender says: "WOAH YOU CANT BRING THAT HERE"
The man goes: "don't worry this crocodile is tame, look..."
He proceeds to unzip his pants and puts his dick in the crocodile's mouth. The crocodile doesn't even react. The man then goes "Anyone else want to try?"
A few seconds pass and then a drunk man at the bar replies "Sure I'll give it a go, but I don't think I can open my mouth that wide"
