What a tough task to find an age-appropriate toy for a theoretician. Well, he needs some perfume, because he has spent the last drops to wash the keyboard of his office PC - the previous colleague left "fingerprints", resistent to all solvents, except to Paco Rabanne (or how is it called?).

I am also thinking of something more sophisticated, like this plush toy

http://www.scienceline.net/product_...products_id/861 There are models of bacteria, viruses and fungus causing TB, common cold plague, athlets foot, African sleeping disease and so on, a cute beige louse about 15 cm long. However I'd find a good T-shirt for him.

Yesterday I saw a guy wearing a nice T-shirt, the only problem for a guy was that he must underestimate the people's attention to the mouth of a person who wears the T-shirt and the questions in their eyes. He seemed unhappy about his own trick. On the T-shirt there was a simple smiley with a grey cat's tail sticking out of the smiley's mouth. The insсriрtion said, "I eat pussy".
