Bathroom break.

If you ever find yourself locked in a bar bathroom stall because you're too wasted to work the latch, your options are kind of limited. Most people in that situation would probably just bite the bullet and crawl under the stall. You'll probably get your clothes messy, but if you've just used the bathroom in that condition, odds are you've already got piss on your pants. At least the crawl will provide you with a plausible excuse. Plus, you'd be out before a crowd had time to gather to see for themselves if the story of the guy too drunk to get out of the bathroom stall was true.
