"It's sink or swim"

A man walks into a bar with a big grin on his face, and the bartender asks "So why are you so happy?"

"Well, see I own this boat, and then this blonde chick comes over right? Tits that reached out this far, and she asked if the boat was mine. I say yeah, and I tell her 'I can take you out to middle of the lake'. So we do, and then I tell her, 'You have to have sex with me. Otherwise it's sink or swim'. And she couldn't swim!"

The next day, the same man comes in with a grin to rival the last one. The bartender asks "Caught another one?"

"Yep. Today, this redhead chick comes up to me and asks me if the boat is mine. Finest ass I've ever seen. I told her she could ride it into the middle of the lake, and we do just that. When we get there, I tell her 'You have to have sex with me now as payment. Otherwise it's sink or swim'. And she couldn't swim either!"

The day after that, the same man comes in, but with a frown. The bartender asks him "What happened this time?"

The man replies, with a slight shudder in his voice:

"Today, a brunette asks me if I own the boat. Mind you, this girl has it all. The tits and ass to die for. I tell her you can ride the boat into the middle of the lake. We do just that. When we get there I tell her 'You must now have sex with me. Otherwise it's sink or swim'. Then she pulls down her pants, and reveals a dick that touched the floor. And I couldn't swim!"
