I have a good idea.

Tear a hole in your rug, and take a small hammer and begin to chip at the floor until you have a tunnel. Then climb in your tunnel and put in a couch and a t.v. and stash your bong there. And a fridge for the munchies. And a computer for cannabis.com. Then put a switch on the ground that reveals the bat cave and a staircase and impress the ladies.
