25. 'Young Frankenstein' (1974)
The scene:
The Monster does the ol' soft-shoe

How best to describe the comedic climax to Mel Brooks' classic horror spoof? Easy -- "sooper dooper." Dr. Fronk-en-steen (Gene Wilder) and his man-made monster (Peter Boyle) soft-shoe their way through an old Fred Astaire standard -- until a shorted-out stage light threatens to ruin their budding showbiz career. Thanks to this flick, who today can recall the chorus of songwriter Irving Berlin's chestnut with a straight face? (On the flip side, let's not blame Brooks for Taco's 1983 synth-pop cover/hatchet job of 'Puttin' on the Ritz.')
