A Zoo Full of Asshats

How loud can two men scream "Fuck!" at the top of their lungs trying to make eachother laugh?

"Who gave that fucking guy an axe? He looks like a dumb prick", you scream at the executioner from the front exhibit while he waits for his girlfriend who works in the gift shop. He's nonplussed and has a dumb tattoo from when he was a teenager.
