The funniest music cue in cinema

There's a scene where Jason Robards is drunk and getting off a bus. The composer seemed to think that music was needed to make him look more of a loser than he was. Thus this hilarious jazz harpsichord starts playing to the sight of Robards throwing away his newspaper and limping down the street, smacking his leg with his cane. You really have to see it to appreciate how funny it is.

There is no "off" position on the genius switch.
