in 1984 ( 27 years ago?! yikes!!) I rolled an 18/00 for a fighter legitamately. since then the closes is an 18/96 in 1986. Then I never could do it again. *sigh*
I see the big deal about rolling the 18/00 for the first few levels, but since the first STR booster item was Gauntlets of Ogre Power also STR 18/00, I always did assume this was intended to level the field later on. While its true there were no guarantees on getting any specific item back in the day, when the lowest booster bumps you up to human maximum, that is a fairly big nudge, nudge, wink-wink .
I was in a Dark Sun campaign with only two players. The DM had us make up our own character classes (from the 2E DMG, I think). We rolled 3d6 in order. In front of both of us, the other player rolled an 18/00 Strength and an 18 Intelligence. Then he rolled 00 to give his character psionics. That was a badass fighter/wizard/psionicist.
I played an illusionist/thief with a 16 in Dexterity. I think my Strength was 7.
I think I count 33 legitimate 18/00, so that means there should be 712,800 characters out there without it (just using statistics).
My brother who was really lucky with the dice did it, he also rolled maximum human size and weight using the alternate rules in the DMG. So he was almost 8 foot tall and over 400 lbs. Just enough to not take size L damage from weapons. He named him Hercules.
Then the party entered a dungeon. He took point, relying on his infravision to spot dangers. Come a room temperature danger and he died without ever striking a blow!
