The year after I finished high school I was in my old neighborhood and drive by a cheerleader carwash...
My buddies and I headed to the closest construction site (no one was there as it was a Saturday) and I drove my Jeep through some massive mud puddles. By the time we made it back to the carwash the Jeep was dropping massive clumps of muck all over the road, and you couldn't tell the original colour.
The chicks did a horrible job on it, I had to rewash it after, but the look on their faces was priceless
