Name That Weird Invention!

It's time for another edition of Name That Weird Invention! -this time with a decidedly Halloween theme. Steven M. Johnson comes up with all sorts of wacky inventions in his weekly Museum of Possibilities posts. Can you come up with a name for this one? The commenter suggesting the funniest and wittiest name win a free T-shirt from the NeatoShop.

Contest rules: one entry per comment, though you can enter as many as you'd like. Please make a selection of the T-shirt you want (may we suggest the Science T-shirt, Funny T-shirt, and Artist-designed T-shirt categories?) alongside your entry. If you don't select a shirt, then you forfeit the prize. Good luck!

Update: Congratulations to our winners! T-shirts from the NeatoShop go to Barking Bud, who called it a Mortalcycle, and John P, who came up with the name Moto-Crossbones by Bone-Daddy Bikes (which comes in "his and hearse models"). Honorable mentions: Elizabeth
(Bone Chopper), Hannah (Tyred of Life), Saudia (Nutcracker), Heather B (Dirt Nap Bike), deathbyawesomeness (diecycle), Sasha (BMXoskelton), and ladybuggs (The Grim Chopper).
