Dilemma which occurs when you need to shit but are far away from the nearest toilet. Running will get you there faster but the natural laxative qualities of running will make you want to shit more. Walking doesn't make you want to shit nearly as much but it takes you twice as long to get to the toilet. Hence, you are caught in a Catch 20-Poo.

When you gotta shit really badly, however running to the toilet will make you shit yourself, but you won't make it if you walk.
I'm a block away from my house, and that taco bell is starting to kick in... I'm in a real catch 20-poo!
