 CONT: During the fight with the fire hose, Frank throws the hose at  the guy going up the stairs and you can see the hose wrap once  around the escaping bad guys right ankle. When Frank pulls on the  hose and drags the villain down the stairs, the hose now has a knot  in it to keep the hose wrapped on his leg. When the villain gets to  the bottom of the steps, the knot is gone and the hose is once again  just wrapped once around his leg.
