It's Always Sunny in Philadelphia - Frank and Liam McPoyle Gun Standoff

Frank has an ace up his sleeve when the McPoyle threaten him. Fun Fact: Frank's line when he pulls the gun on the McPoyles ("Yippie ki-ay, Mr. Falcon") is a reference to the infamous censorship of Bruce Willis's line "Yippie ki-ay, motherfucker" in the TV version of Die Hard 2. Also the scenes with Frank beeing in the vents with a zippo lighter are a tribute to the Die Hard 2 movie.
