Speaking of trembling knees..Nice one, katlaughing! This is not my own story, but it is about trembling knees:
On a TV appearance, a famous Norwegian fiddler was going to play an old folk tune. He got on stage, and after having looked around for a while, he got down off the stage, grabbed one of the chairs intended for the audience, brought it back onto the stage and sat down to play. The TV host asked him, somewhat confused " I thought you folk musicians played standing up?" Your man answered "No, we're too nervous. It's only the Swedes who stand up, they're too stupid to be nervous!"
Good thing it isn't just me who's got trembling knees!
Magpie(who has got nothing against Swedes, but couldn't help laughing all the same)
