You know, I watched Cabin In The Woods and when the stoner guy is introduced I was genuinely like "holy fuck Shaggy from Scooby Doo is in this movie?? The fuck??" But it turns out he's not. But I swear he's based off him. I mean he practically pulls up in a Proto-Mystery Machine.
I forget who plays him but if Matt Lillard didn't exist he'd be a dead ringer for a live action Shaggy
