Gone nuts?!

Last week you liked the thick brush outlines. So this week I drew some fine lines. Well, always do the unexpected ... I did the scribble for this one after reading some ancient MAD-magazines. For me the best loo-reading available on the market!

At first I suggested that he went mad about some stock exchange stuff. OK, I admit that's boring. Then Thies came up with the idea that he might be watching the ladies at the aerobic course. Much better. Well, but maybe Jensemann is right and a female colleague just dropped a pencil ...

I'm open for further suggestions.
