The "Beverly Hillbillies Parody" is a song sung by Tom Servo and Joel Robinson during Experiment #103. It is a parody of "The Ballad of Jed Clampett", the theme to the TV series The Beverly Hillbillies.
Come'n listen to a story about a man named Jed
A poor mountaineer barely kept his family fed
Then one day he was shootin' at some food
And up from the swamp came a big ugly dude
Wolfman, that is.
Well, the next thing you know, old Jed's really scared.
The kin folks said, "Jed, get away from there!"
Said, "My cabin is the place you outta be,"
So he loaded up his drawers and he told his family.
