Everyone’s had that horrible moment once in their life when they just had to go to the bathroom, yet couldn’t. Maybe you were stuck on a wide-open stretch of highway, or enduring the spasms of your bladder on an airplane when stuck in a delayed landing pattern. At first, you try to ignore it, but pretty soon, you can feel it practically bubbling up in your stomach, swimming around your molars. You’re certain if you don’t vacate immediately, geysers will start spraying out of your ears like a cartoon character.
