Fun drabble (100 words exactly)

From theatrical_muse: Write a drabble about fun.

It was fun on Avon's birthday when I gave him some foil-wrapped chocolate coins and left them in his desk drawer. Then, just to continue the theme, I wrapped his chair and desk and everything on it in foil, even his tools. (The teddy bear dressed like me was a bit worrying).

I think it ranks with the time I filled his cabin on the Liberator with inflated plastic bags. But the best was when I bolted all his furniture to the ceiling. You could hear him yelling from the flight deck.

Pity I'm never there to see it though.
