Number 15 the SPPC
The SPPC is a hotly debated philosophical debate among the high ranking intellectuals of the special Ed division of lowry.

The conundrum can be explained as:

Should you find yourself trapped and forced to choose either to:

A) Having someone piss in your mouth B) Having someone poop in your chest

The person doing this to you is british.

Pee contains toxic compounds like Urea and Uric acid.
