As you can see, the heavies are probably members of Hank Scorpio's diabolical Globex Corporation.
Either that, or they're Chinese traffic cops.
(If it's the latter, then we can safely conclude that SOMEONE decided to live dangerously, and didn't put enough change in the parking meter.)
Not to spoil the surprise, but I hear that after a breakneck Segway chase, Mutt and his companions escape by falling off three waterfalls and swimming through a green algae bloom.
(Green algae? Ewwww)
Still no word as to whether they manage to jump a shark or two along the way.

UPDATE: Heh. Don't think of them as Segways -- think of them as "Anti-Terror Assault Vehicles". (Hat tip to Jonah Goldberg)
UPDATE #2: "Who said it wouldn't be a 'Green Olympics'?"
UPDATE (Jul 6/08): Whoops. It's supposed to be "Segway", with no "d". Stupid phonetic spelling system!
UPDATE #4: I did not know that: The father of the Segway's inventor is apparently Jack Kamen, one of the illustrators of the old Tales from the Crypt comic book.
