I really don't see how you can equate a homemade bong with a handjob in a movie theater. Sure, it's not going to impress all your friends like a $200 glass bong would, but impressing other people isn't really what I smoke for. If I had the kind of money to afford something like that, it would be great, but in the meantime if I can put together something that will work pretty well from household materials I don't see how that's somehow repugnant and unclassy. Sometimes people want cool, filtered bong hits without spending a wad of cash on a fancy piece.
