I don't think this thing belongs to the town topic, but if any Admin says it does, feel free to move it :)
I did this Ratrod based on the LEGO Set 60333 Stuntz bathtub bike (The best Lego set ever btw) and the 1960s "The Bathtub..." custom rod.
I did an exaggerated siamese double V8 motor (maybe I should call this a W8 motor?) full of chrome.
An exclusive driver "throne" seat, with a biological 'easter egg' inside, flush box, toilet paper, horn, and channeling valve as a handwheel.
I use some "useless" parts like the two-toned/marbled (Red/Yellow) exo-force projectile disk
Two bathtubs with showers, a Chromed hot-water tank on black, or a fuel tank, you name it.
