How 'bout good commercials which vanish?
1) The "I hired 3 girls from the middle school to keep me on my diet" Geico commercial. Whenever he begins to eat badly the 3 girls appear and say, "You going to eat that?", "EEwwww" and, "That's so gross".
2) The 2 gals go into the young bar and one has a bacon whatever in her purse to attract guys. "You don't think that's really going to work, do you?", "Guys love bacon", her friend answers. Three guys appear...."That perfume is....intoxicating" while the second girl looks on in open mouthed disbelief. Hysterical.
Too many people to pay?
3). The, "Would you pass the jelly" for the All-fruit (presumably superior jam) and the table goes into shock and the little girl laughs at the gaff. Brilliant.
Again, I think they used real actors who want to get paid for their work. They actually remade that one with lower production values.
