Jack herer( R.I.P) at a vegas trade show, cool guy but man would put like half the pipe in his mouth when he smoked. Glad I hit it before him
A couple guys from kotton mouth kings, I honestly could not tell you who, I think they suck and never liked em. But my brother and his gf wanted to go to a signing at the record exchange back in idaho. I was forced along, anyway long story short we were an hour late, all the fans were gone but 3 of the kmk guys were walking around lookin at cd's, bros gf recognized them. It may have been because she was hot but they were pretty chill about hangin out took us on the bus and they matched joints. She still has the video somewhere.
And it doesn't really count but jack black at a tenacious d show. Joint got passed to me, I took a rip an toosed it on stage he picked it up, hit it, and flicked it back into the crowd. But I don't think that counts.
