It's been a while since we saw a goober joke on the CleanLaugh list. For those who don't know what a goober is (according to me) you can see a picture of one at:
A goober was playing Trivial Pursuit one night. It was her turn.
She rolled the dice and she landed on "Science & Nature." Her question was, "If you are in a vacuum and someone calls your name, can you hear it?"
The goober thought for a time and then asked, "Is it turned on or off?"
