I remember that I posted back in August that I had gotten 1000 plasma grenade kills and had 864 grenade stick in Halo 3, and figured I'd post the numbers that I just got to, cause to tell you the truth, I'm rather surprised at the numbers myself....
Anyhow, from Bungie.net:

3033 grenade sticks!! I have been averaging around 5-6 lately per game, some of them rather video worthy cool sticks

And, I've gotten 3033 sticks in only 1539 games (which, I'm sure the totals will only keep going up as I get games in)... I currently have 3775 plasma grenade kills...
That's 3033 times someone wound up with something glowing (or hissing) on them and cursed my user name
