Ah, an interesting topic indeed. I'll stick with the 5 fomula. Not sure if any of these besides MJ would smoke with me, but ah well:

1)You of course, MJM. You're a blast. Plus, you're very understanding, and that's a rare quality in humanity these days. Good friends are hard to find.
2)Ghost - He always has something thoughtful and/or funny to say. Makes for an excellent toke buddy.
3)Psychocat - Pretty cool guy. Level-headed and forgoes any bullshit. Plus, his car is the shit.
4)Penguin - Well he might be almost 10 years younger than me, but I like the kid. Would smoke with him anytime.
5)Tilde - Seems like a cool dude. Good sense of humor and good taste in music. And music and humor are always important when high.
