Everyone knows that Hummers are pretty damn big, but now they can get even bigger with Grow Your Own Hummer! Okay, I really doubt that this toy could get bigger than an actual Hummer, but who knows—those inflatable water-sponge things seem like they can defy the laws of physics.

This novelty comes in the H2 variant of the Hummer and is available for $24, in packs of a dozen—just in case the first five or ten don't get quite huge enough for you. [Grow Hummer via neatorama]
