So I get to keep my bike by my desk (software developer) and just had this idea. When I use the bathroom at work, instead of tossing the paper towel from drying my hands in the trash there, I bring the now moist paper towel back to my desk and use it to clean my bike. :-) It's a bit of a time waster, but after not having cleaned my bike in several months, now I'll have it nice and clean in a few days, and that makes me happier than being at work.
