I had a former co-worker (one of the laziest people I've ever had the displeasure of working with) who rode in on a bright yellow, Mike's Hard Lemonade branded double-boinger one day, locked it up in my parking spot (not really mine, but I did lock to that signpost every day), then never touched the bike again. He spent the entire day complaining about how sore his butt was and walked home after his shift.
His work/bike averse ass was fired in August, but the bike stayed locked up out front of the cafe until November, when I removed the seatpost and rear brake cable (which is all that the idiot had strung his lock through) so that another co-worker could adopt it as his bar bike. I think the U-lock stayed locked to that post until the following summer.
