Okay, couple I confess I used:
1. Hi. When are you going to take me home?
2. Wanna take a shower?
Careful with the second one, it got me a beautiful wife.
At a Jimmy Buffett concert, inside Margaritaville, we were standing in line for some beers, and my friend's husband said to the girl next to him:
"I like your shirt." To which she said, "I like your shirt." To which he replied, "Wanna trade?" She said sure, and took off her t-shirt. She was not wearing a bra and had the most amazing breasts I've ever seen (her face was butt ugly, I am pleased to say).
He put on her tshirt and said, "I believe your shirt is too small for me." To which she replied, "Want your shirt back?" To which he replied, "Yes."
So they exchanged shirts again.
This in front of about 50 folks. Got to be the most hilarious thing I've ever witnessed.
