Does it count if I rode to work, realized I forgot my chain, rode back home and decided to just work from home instead? If so, feel free to read on. If not, feel free to read on anyway. Ride in was nice. I passed a couple messengers leisurely making their way to work and passed another commuter. Realized I didn't have a chain when I tried to lock up at work, thought of the Dumbest things you've done commuting thread, then jumped back on my bike and rode home.
