There are many reasons to like Sheryl. You'll have to admit that sex sells, I mean, there are other characters out there who haven't gotten that much airtime, but they have big boobies and that makes them popular. But Sheryl has both the body and the attitude, and as someone mentioned, she's professional and that rocks. Not to mention, she knows what she wants, she's not shy on guys (c'mon, guys like that right?) and she's pretty too (in the context of the animation of course).
