Got a problem with why something stopped unexplainably in the distant past, like dinosaurs, ancient civilizations, ice ages, what have you? Well, call Dandy Bob, the Fix-it Man, and he will, for a special low fee just for you and which expires one hour before your dissertation is due, fix you up with a special, guaranteed to be unprovable and irrefutable, earth shaking (haha) and ultimately irresistible gen-u-wine Comet Theory to prove that destruction of all that was but is no more was just a bolt from the heavens!
Hurry, hurry, operators are standing by the phones, first ten callers get authentic "Photos from Space" that PROVE, yes, PROVE that there be strange bumps in the ground somewhere in the general vicinity of that thing you need an answer for that might be, er, must be the elusive FIREBALL FROM THE HEAVENS that will get you and your theory into the scientific textbooks!
But don't let that stop you from being condescending as to real scientists - it helps identify which luddites shouldn't be listened to.
