Fill In The Blank: Maybe they aren't really brothers?

Fill in the blank in this quote from Steve Greenberg, the CEO of S-Curve Records:

"Very simply, the Jonas Brothers are different than every other Disney musical act because the Jonas Brothers ______________________________"

a) "were actually built from the ground up by the Disney Imagineers."
b) "were a band first"
c) "were actually aliens, just like that episode of The Middleman"
d) "have at least one band member that can play their instrument"

Hmm... there's a better joke in here somewhere.
