"For Whom the Bell Tolls," by Steven Baker and Carmen Daye (the song played in the theater).
Honestly, most of the soundtrack counts.
This movie has two. When he tells Ms. Farmer to "forcibly insert the lifeline exercise card up her anus" and when he calls Patrick Swayze "the fucking antichrist."
Him laughing as a jet engine is about to crush him, especially as he's repeated stated he's scared of death...
