Hee - one of my (now ex-) colleagues had a bike WAY more expensive than mine, and he used to bring it into the exercise/weight room while he was showering, then took it up to his office for the rest of the day.

I hid it once, just wheeled it round the corner while he was in the shower. Poor guy came tearing out of the mens locker room 2 minutes later wearing only a towel. He had heard the ticking of his expensive drive train from UNDER WATER.

So sweet, just like a new mother
