Two people are trying to solve a problem and can't, for the life of them, figure it out. They may be cops solving a murder, prisoners devising an escape plan, or scientists battling an alien invasion. They have been at it for a long time, pouring over dusty old books, looking at photographs writing formulas on the chalk board and time is ticking down. One of them says "I'l be right back. Gotta take a leak." "What did you say?!?" "I gotta piss" "Thats it's it!!! The answer was staring us right in the face!" As it turns out, the murderer snuck up behing the victim and stabbed him while he stood at the urinal or the prisoners can tunnel through the wall and escape and through the sewer pipes or human urine was extremely poisonous to the aliens and they could kill them by pissing on them.
