Old Swiss joke: ( this is best told, but whatever)
A mountaineer finds himself lost on a trek and comes across a lone chalet where he knocks on the door and asks for shelter. The owner welcomes him in, his wife feeds him and says he can have the bedroom next to his young daughter for the night.
This is too much temptation for the mountaineer so he sneaks into the daughter's bedroom and makes passionate love to her, and the next morning when her father finds out he seeks out the mountaineer, but he had already left and was half way across a mountain pass.
The father rushes out of the chalet, sees the mountaineer in the distance and shouts to him "Did you make love to my daughter?!!!"
And the mountaineer yodels back................"And your old lady too!"
(I have a cruder one than that if anyone is interested)
