What's The Weirdest One-Off Work Vehicle?

Sometimes you just need a singular tool for a singular job, so you make a one-off vehicle. Necessity is the mother of invention, and there are some weird ass mothers out there. Show us the craziest one you can find.

I'm going to get the NASA Crawler-Transporter out of the way (also, there are technically two of them). Built in 1965, the nearly 6-million pound tracked vehicle is basically a slowly moving platform designed to move heavy space vehicles to the launch pad. Unique, weird, awesome.
