Ha!

Had the following exchange at the gym when I finished using one of the machines:

Random Father: Excuse me, are you done with that one?
Me: Yep, it's all yours.
Random Father's Son: Aw, man, you couldn't say no, could you?
Me: Sorry, dude.
Father: Tell you what, you only have to do the weight she was doing.
Son: [wary] What weight was it?
Father: 75 lbs
Son: No.
Father: Are you saying that a woman, a girl can do more than you?
Son: Yes. Yes, I am.

I may have laughed out loud.
