Gimme what?

On the way to work yesterday, while chatting with M via cell phone, I came up behind a big construction truck towing a little trailer with a compressor. My guess is the brand is supposed to be GrimmerSchmidt Compressors, but some enterprising person removed some letters and made it far more funny.

Please forgive the image quality. I was doing 60 shooting a dinky BlackBerry phone cam through the dirty windshield while steering. Good to know that I'm willing to risk my life to bring a little potty humor to the masses.
