Lend Me Your Ear

Somebody once asked me to lend him my ear.  I told him that under absolutely no circumstance would I do that, since he had two perfectly functioning ears and had no need for a third.  I also pointed out that it was rather odd to ask for me to loan him my ear; what was he going to do when he was done with it? Just hand it back and say, "OK, thanks, you can have it back now?"  Apparently he thinks that all artists are like Van Gogh.  Well, we're not.  Some of us are rather fond of all of our various body parts being ATTACHED, thank you very much.
