The aircraft carrier

You pick up a mop out of a bin full of soapy water and charge out of the closet. You hold the pointed end of the mop out like a hockey stick and catch him square in the gut. He grabs the mop with both hands but you twist it around like your would a twirling baton. He loses his grip because it's not physically possible for his hands to twist that way. You regain control of the mop, simultaneously swinging the wet, soapy end into his eyes. Blind and winded, the guard doubles over and falls on his back. But he has already called security, for lots of footsteps are now clunking down the stairs at an alarming pace. There's no other option than facing the 5+ guards (each carrying the most high tech guns at the time) with your soapy mop. Of course, that doesn't end well.
