Staircase bong
Read this on lowbrow.com (great site, think overheardindublin.com but more, well, depraved):
not mine, but this needs to be documented here for sure:
i have this friend, he works with his dad, doing carpentry and stuff, dad specializes in ornate staircases.
Did a staircase for his buddy once, a sweeping curving grand staircase kind of thing.
it was a BONG.
pack it at the bottom, smoke it at the top, whammo your smoking out of your house.
that man is my personal hero.

I wonder if you could rig a whole house with piping, structured cabling style, for easy bong access in any room?
