We just lost half the party to bad dice rolls. I was the barbarian/tank, and we were fighting a high-AC, high-DR critter. They were all assisting me with something like a total +8, so I could use full power attack. That evening, I rolled three 1's in a row, and two 1's in a row twice, in addition to repeated single 1's. I never rolled a 20, all night.
Since we play "critical fumbles", I spent most of the evening recovering my Greataxe, getting up off the floor, watching my buddies die, etc....
Just about the only thing that saved us was the DM rolled fairly poorly, too. Not as bad as I did, but still....
The really scary part was that a few nights before, one of the players (a survivor, actually) got into bed with his already-sleeping wife, and she murmered "beware the round blue dice". We joked about it up until I started rolling all the 1's with (you guessed it) my blue 20-sided dice.
