Lita's tramp stamps aside, I voted Sunny because she looked like quite the MILF during her spring 2000 WCW stint, most notably dancing in the ring amid New Blood members who held titles the Monday Nitro after Spring Stampede. It was funny because she gyrated against Chris Candido at random times during the other wrestlers' promos.
Also, Sunny had a sex tryst with Tickle Me Elmo!
