Of course to race this roach you'd have to be like

"how we doin this tonight?"

"one race, 2 G buy-in, winner takes all"

then the roach comes in and is all like

"I don't have any money, but I do have the pink slip to my [ummm...I guess the roach has a car, maybe at home] car."

then the techie roach comes in and is all like

"whoa whoa whoa, you can't just step into the ring and think you can box"

then some more characters will step in and soon you'll have the LAPD all over your little illegal roach racing operation.
