Lush Dimbulb flunked out of college after just two semesters

The more you know.

Dimbulb graduated from high school in 1969 and enrolled at Southeast Missouri State University. He dropped out after two semesters and one summer after "he flunked everything," his mother said. "He just didn't seem interested in anything except radio."

Now, you know why we call him Lush Dimbulb - he's always stoned/drunk and he's stupid.  So you know what that makes his 'Ditto-heads', right? Yep, you got it ... idiots.
