Sad thing is, these awful "commercials" or "info-mercials" would not be around if people weren't buying the stuff in the ads.
My favorite was from about 11 or 12 years ago....Where this "ab guru" would have a "Kung Fu master" put a cinder block over his abs, and then smash the block with a sledge hammer........the audience was all terrified, as the "Kung Fu master" says to the ab-man, "I cannot gurantee yo' safa-ty" and the ab "guru" spits out his classic line- "the Abflex will guarantee it".
Fucking hilarious.
EDIT: Hey, we can say Fucking again?
