Homely nurse is prepping a male patient for hernia surgery. She shaves half his crotch, then leaves the room, laughing.

"What's so funny?" asks a pretty nurse she encounters in the hallway.
"That guy," she replies, "he's got the littlest dick I ever saw. And not only that, he's proud of it--he's got a tattoo on it that says, 'TINY.' "
"You're kidding," says the pretty nurse. "No, I'm not," says the homely nurse. "If you don't believe me, go in there and finish the job."

So the pretty nurse goes in and shaves the other half of the guy's crotch. When she's done, the homely nurse is waiting. The pretty nurse says, "You were wrong. The tattoo didn't say 'TINY,' it said 'TICONDEROGA NY.' "
