I pulled one almost as dumb as that, so don't feel pregnant. I changed oil, started the motor and let it circulate, then shut it off to check the sight glass for final top-up. After I added a few more drams, I took off for the car wash to do a pre-trip cleanup, and FORGOT TO PUT THE CAP BACK ON!

By the time I figured out what had taken place, the whole right side of the bike, not to mention my boot and pantleg were drenched in brand-spankin' new 8-buck-a-quart Mobil1 4T. Luckily, the wife was nearby busy spending me into the poorhouse, so I called her and had her meet me at the carwash with a can of degreaser. Only lost a pint or so of oil, but it took several washings to get the oil off my jeans.
