haha, more often little kids than old people, I've had a little girl tell em I smell like a skunk after a safety meeting.
I'll add
"why are your skis so wide? does that help in the moguls?"
"those look like water skis!"
"how long are those skis?"
"you should be wearing a helmet"
"my 219 rossi's sure were fast back in the day"
and I don't know what it is about our mountain, but we get a lot of trashy dads who call us "park rats" out for the dumbest things, and completely out of the blue, like in the lift lines "why do you punks dress like that? you think you're tough or something?" to which I'll usually reply "I'm the best skier on the mountain, I can dress however I want". It usually rustles their jimmies. I'll always give respect when I get it but these old guys feel like they have to look tough in front of their Jersey trash wives or something.
