Al: Well, we've put in our redwood racks. Now, if you're on a limited budget, you can substitute PVC pipe for the redwood.
Tim: There's Marcy right now. Marcy, what do you think of your new wine room?
Marcy: Oh, it looks terrific. But these shelves are so tall. Are you sure they won't tip over?
Tim: Not a chance. I fastened these to the walls and floors with seven-inch bolts myself. Added some extra weight here for stability.
Al: Good thinking, Tim.
Marcy: Well, I love it. And to commemorate the occasion, I'm going to add this rare '56 Mouton Rothschild.
Al: Okay. Now, because of the added weight, we've also taken the precaution of reinforcing the floor.
Tim: We did?
Al: Didn't we?
Tim: I didn't. Did you?
[After a creaking sound, the wine rack falls through the floor.]
