Now, this was the most "controversial" MSB yet! After discovering that 95% of the entrants were guessing "It's A Gas" by Alfred E. Neuman, I decided to add a cryptic clue ("Use your NOSE or you'll be WAY off") to help matters a bit.
Turns out this "burp" is from "WEIRD AL" YANKOVIC's "SMELLS LIKE NIRVANA"! Actually, as Jon "Bermuda" Schwartz tells us, the sound is "about 3 or 4 sounds layered -- and the 'burp' is a sample of White Fang from an old Soupy Sales LP"!!
CONGRATULATIONS go out this week to Oscar "Vermin Boy" Goff of Templeton, MA, whose entry was selected by random draw. He wins a copy of the demented song of his choice.
