"Swingin' Six" ZIP Code Video
4 good reasons (because I'm an overachiever) to riff this short from the 1960's about using ZIP codes, found at https://youtu.be/QIChoMEQ4Cs:
1.This is an actual US government short. If you don't riff it, the terrorists win.
2. Cavemen. Not sure what it has to do with the postal service, but cavemen. Occasionally in very short skirts (yes, still the men).
3. To find out why not using ZIP codes will make your true love desert you.
4. They rhyme 'question' and 'indigestion' in a song. Oh, did I mention it's a musical?
