He's probably wearing crotch shielding kevlar impregnated red plaid thong underwear like all the lumberjacks do... so no problem. He's a lumberjack and he's okay.
When I first heard this joke, a native American was the dummy: An Irishman goes into a shop and buys a chainsaw. Two weeks later he returns the chainsaw and says to the shop assistant: "2 weeks ago I bought this chainsaw and you said that it would chop down 50 trees in a day. I can only manage 2 trees." The shop assistant says, "let me see", and starts the machine up. BRRRRRR!!! The Irishman jumps back in surprise and says "what's that noise?!?"
First time I heard it ... it was a Polack... I used to tell a LOT of Polack jokes until a 6'6" 400# Polack tapped me on the shoulder in a bar and told me he didn't like Polack jokes. THAT was the end of THAT.. Never told another one
