TRUE LIES (1994)
Secret agent Harry Tasker (Arnold Schwarzenegger) never backs down from a fight … even if it disrupts a much-needed leak. Tasker gets ambushed by two extremists while he’s taking a whiz and then goes all Arnold on the bad guys, finishing one off by smashing his face into a urinal, flushing it, and saying,
“You won’t be back!” “Here, cool off.” The moral? Always have a water-related one-liner in the chamber whenever you’re using a public bathroom.
