Sheldon: Oh dear! There it is again. Do you feel it?
Howard: The growing realization that you are one wacky bastard? Yep.
Sheldon: No, the vibration. We are directly underneath the Geology lab and they're running their confounded sieve shakers again. Hey gravel monkeys! If you need to shake rocks, try jiggling your heads around!
