So happy I found this thread! Read through all 10 years of it! The idea to look up Mad parodies popped in my head after watching Hello Dolly on TV, and remembered bits of Hello Deli. Lo and behold, I found it here.

Does anyone remember one about geetting high or drunk that was sung to Skip To My Lou?

It went something like,

Sniff, sniff, go sniff some glue
You'll take off like a DC2...

There was something about Schlitz brew at the end too.
