You're at a bar with your buds and realize that the three (or was that four?) pints you downed have worked their way through your system, so you're heading to the pits to relieve yourself. There's just one corner left, then a short straight and you're good to go. But you apex too early, clip the corner, trip on the baseboard and spin out into the wall. Next thing you know, you're splayed on the floor, wondering what just happened. Looks like you're done for the day. Good thing you've got a tow hook installed.
