8. Evil Bong (2006)
A group of stoner college students purchase an old bong, that when used transports them into a different nightmarish realm from which they find it difficult to escape from. With its stereotypical portrayal of stoners, the director proves that he has never even been in the presence of a joint being smoked, let alone a bong. The film is so bad, you couldn't even enjoy it stoned and it is very obviously trying to be the coolest stoner movie ever. Obviously trying to gain some stoner credibility by having Tommy Chong appear at the end, this does not mitigate the inherent crapulence of the film. You will need to switch off your intelligence for this one and wallow in some very unfunny waters, as well as suspend your disbelief about possessed bongs.
