A while back in college I had a couple friends that worked at a local water park. So, on their day off they decided to go to the water park and generally annoy all of the other lifeguards that were on duty that they know, several of whom are female (obviously).
So, one friend says to a cute female lifeguard:
Friend: What time do you get off?
Lifeguard: Around 5.
Friend: Can I watch?
