Hallelujah! Holy shit! Where's the Tylenol™?!?"

This hillarious rant by Chevy Chase is one of the gratest moments of National Lampoon's Christmas Vacation (IMHO). I have made many an attempt to memorize it, but I can't keep a straight face whilst reciting. I am convinced that using this as a monolouge for an audition would get you many a part.
