There has been much debate whether Neicy Nash, who plays Deputy Raineesha Williams on Reno 911, really has that big of a rump in real life. She has said in interviews and dvd commentary it is indeed a fake. And you'll notice when she comes out in the Tyra-inspired swimsuit that the skin tone on her legs doesn't match the rest of her body, plus the back of the knees crease in an unnatural way.
Tyra: I'm told that you--there's a special way to frisk someone. And that I should know how to do that. And you guys are gonna teach me that.
Lt. Dangle: Well, we're Master Friskmen. Master-Master Friskmen. Uh Travis, will you do the honors?
Deputy Junior (pointing at Tyra): I'm gonna frisk...? I get to...? You know, I've had this dream four times!
