Air Plane:http://www.garnersclassics.com/wavs/ironboot.wav
Monty Python and the Holy Grail:http://www.garnersclassics.com/wavs/holy/scratch.wav

Christmas Vacation:http://www.garnersclassics.com/wavs/nation/levdead.wav
Tombstone:http://www.garnersclassics.com/wavs/tomb/double.wav

Blazing Saddles:http://supak.com/store/videos/sounds/brooks/cleavon_little_whip_this_out.wav


These are all really funny movies, if you havent seen them I would recommend you seeing them although, Ausitn Powers is a little ronchy.
