Having said all that. Sounds like I still would have laughed at Jack in the Box commercial. Haven't ever seen it on though...
don't think it's the "idea" of the commercial that makes it funny... i think it's more about the faces and the way the "stoner" in it actually says his lines... it's like if he was extremely baked and all slowly like is like "yea! dude that's what i was gonna say!"
