To fail amazingly badly at a basic or simple task. Infomercials use this kind of exaggerated, highly unlikely failure to demonstrate the nonexistent or dubious "problem" the product in question supposedly solves (i.e. trying to crack an egg into a bowl and instead splattering egg and crushed shell pieces all over everything within three feet, hammering a nail into drywall and sending the hammer right through the wall, eating a sandwich and having its entire contents fall directly into your lap, etc.).
Just full-on infomercial failed at cracking an egg. Twice.
