VPI is bringing back the Magic Brick!

So, I am in Manhattan on a shopping errand jaunt with my wife. We were at ABC furniture downtown, made our way up through Soho, stopped at the old Stereo Exchange (if memory serves, it was the small shop) and bought a stack of VPI bricks. Three- they were heavy. Like an idiot, I’m schlepping these things around town on our other stops. We finally land at the rug floor in Macy’s, and there is a demonstration of guys wearing robes and mystical garb weaving rugs. I stop at the platform where they are working and put down my package with a grunt. One of the swami dudes says, ’that looks heavy, what is it?’ I say, "magic bricks." He nods sagely, like I’m on the same mystical channel, then turns back to his loom.

Was he weaving a magic carpet?

The expression thick as a brick springs to mind.

@bdp24 - yes, i think so. 

You don't want to drop a magic brick on your toes.
