Personally, I never found Willis that hard to understand.
Video editor Robert Jones has spliced together this half-definitive (part 1 of 2) supercut of the greatest catchphrases in TV history for Tastefully Offensive. Personally, I think this goes a little heavy on the sitcoms and a little light on gems like "Omar comin'" or "Sheeeeeit" from The Wire and other heavy shows like that. Catchphrases are so much funnier in serious situations. That said, I love it when a supercut comes together.
I hope people don't ask Jazzy Jeff to do that all the time.
