A friend of mine used to have a 8'x8' smoking shack in his backyard, the thing had a couch,coffee table, lights, and everything. Everyone usually pooled in cash and dro too.
I was in art class a few years back and the teacher was pissed because someone was talking, she walked in front of the class and yelled "I hear voices and I don't know where they are coming from!" never laughed so hard.

I think it would neat to have a bong that looked like a kamehameha blast and have a coffee table with a painting of goku doing the kamehameha with out the blast so you can place the bong in goku's hand.
