Skeptical? Then skip, if you will, to 1:54, when Rogen shoots himself in the face with a "gas gun," rendering himself unconscious, with a plume of green smoke coming from his nostrils -- how's that for a metaphor for bong rips? Speaking of green (and yes, by "green" we do mean "the green"), there's a pervasive current of, uh, verdant imagery happening here. Sure, he's the Green Hornet and all, and that character is not necessarily inherently connotative of weed, but (especially considering the characters are vigilantes living outside the law, good guys who will "pose as villains to get close to the bad guys, that way nobody will suspect we're really the good guys" -- which, just by the way, is great stoner logic) doesn't it make sense to take it there? And if that's not enough for you, listen a little closer. Hear that soundtrack? Yeah, that's a Cypress Hill song.
Consider your mind grapes popped.
