Don't swallow........

[BillyBob]

A guy and a gal meet in a Hospital elevator.

The guy asks, "Which floor?"

The gal says, "Third floor."

The guy reads the list of offices on the wall and says, "Oh, going to give blood, I see."

She says, "Yup, it's worth $30.00. Which floor are you going to?"

He replies, "Sixth."

She says, "Oh, that's the sperm bank!"

He nods and says, "Right! and it's worth $60.00!"

A couple of weeks later, the same two meet in the elevator again.

The guy says, "Well, hello again. Third floor again?"

The gal, mouth tightly closed, cheeks puffed out, shakes her head and holds up 6 fingers.
