This 2006 Mercedes E55 AMG owner and his lawnmower, 1. Nissan 350Z, 0.
This video comes to us from the MBWorld.org forums, where an E55 owner said he had no choice but to smack down a shit-talking Z owner who claimed to have the faster car. And he did it while pulling a trailer with a riding lawn mower on it.
Now, we at Jalopnik normally don't condone any acts of street racing, but this is on the very lame edge of street racing, and they seem to break it off at a fairly reasonable speed. I can't say I agree with this behavior, but the outcome is too funny to ignore.
Back to the tuner with you, 350Z. Maybe one day you'll be able to out-lawn mower-pull that Mercedes. Never give up on your dreams.
