Get to Know Your Farts 11

The "Not Now!" Fart:
You feel the presence of a mighty fart, and are unable to release it due to your situation. Happens on first dates, at important meetings, and on other such inexcusable occasions. You clench your buttocks together so hard that you nearly give yourself a stroke, and wait for the pressure to subside. Success depends on a number of factors, but Sods law tends to win out in the end.
