Hi, I see that you're new to this gym, and I wanna be the first male to bother you.
Boy: "Do you like parties?" Girl: "Yes, why?" Boy: "Well then jump in my pants and have a ball!"
Boy: "Hey baby, what's your sign?" Girl: "Do Not Enter!"
Boy: "You know unlike all these other guys, I can make you really happy" Girl: "Why are you leaving?"
Boy: "Hi, my name is Milk. I'll do your body good." Girl: "Sorry, I'm Lactose intolerant!"
Brrr! My hands are cold. Can I warm them in your heaving breasts?
I wish this gym had a stationary bike built for two.
How'd you like to go on a long romantic walk on the treadmill?
A classic Tommy Cooper gag "I said to the Gym instructor "Can you teach me to do the splits?" He said, "How flexible are you?" I said, "I can't make Tuesdays", was fifth.
