Janie's got a gun... WHAT is the DEAL with THAT?

Didja ever notice how the opening bass riff to Aerosmith's "Janie's Got A Gun" has the same synthetic bassline as the opening to "Seinfeld"?

"Janie's got a gun? Janie's got a gun? Now HOW did JANIE, exactly... get that gun? Did she cut school to get a license first? Did she then hold up the truancy officer with it so that she could get away with both crimes? I mean, if Janie's got a gun, that changes everything. That chemistry teacher's bumping up Janie's grade now. Suddenly, that covalent bond definition looks good enough."
