Cans that can openers don't work on. (usually cheapo beans or tomatoes)
You get a quarter way round and suddenly the next few millimeters stubbornly refuses to give in to the opener , rinse and repeat. You end up with a can with sections open and bits still attached and you have to bloody try and 'nibble' at the stuck bits. The end result is tomatoe speckles all over your previously immaculate shirt, dribbles of stuff all over the now slippery can and a couple of bits that simply refuse to part company with the rest of the can. This results in needing to bend back a section of the half detached lid and when your hand slips either flicking food all over some unsuspecting family member or slicing a lump out of your thumb.
Having finally scraped what ever was in the can out onto the plate you can guarantee someone will hit the jackpot and get the metal slivers down their throat.
