Three guys are sitting at a bar, bragging about the girls they had sex with last night.
The first guy chuckled proudly. "My girl was great in bed," he boasted. "And she has a hilarious tattoo that says 'No Trespassers'"
The second guy scoffed. "That's nothing! My girl was wild!! And her tattoo said 'Authorized Personnel Only!"
The third guy was quietly cracking up to himself. The two look over and ask him why.
"My girl, she was amazing in bed, but it's the tattoo I can't get over!!"
"Why, what did it say?"
"Caution: Slippery When Wet."
