If you had dropped your drawers and gone out in that lake, that guy wouldn't have need to help you but I bet he would have some good advice for you.
I can hear it all now......
"Howdy. I didn't see you at first but then I heard that giant sucking sound so I figured someone had dropped their drawers and gone out into the lake in his skivvies.
Ya' know? That water is just a hair over freezing, coming off o' them snowcaps like it is. Ohh dogies! Ah still remember the first time I did a fool thing like that. That was over 30 years ago and I just noticed another small piece of ice fell off just last Sunday!
Oh. After you get back out and put your britches back on, hunker down near a camp fire for about an hour. Don't let anyone get behind you durin' that last 15 minutes though.
Folks get real riled when they're behind you and all that wind you sucked up finally thaws and changes direction. It'll mess up a fellers hair from 40 feet away.
Like I say, I did that 30 years ago an I still remember how mad that feller got when my blast blew his wifes skirt up over her head. She was a good 50 feet away too!
Don't forget what I said. Oh, and another thing. Don't aim yer rear at that fire either.
Blowing them burning logs all over the place can start a forest fire when you add the gas you got from that empth can o' Pork & Beans I see laying over there.
You have a good evenin' now, you hear?
I got's to be moseying back down the hill before your blast o' wind has a chance to escape. "
