In 1995, when MTV chose McCarthy to co-host a new dating show called "Singled Out", she left "Hot Rocks". Her job as a co-host was a success, and "Playboy" wanted her to do more modeling. That same year she also appeared at World Wrestling Federation (WWF) pay-per-view event WrestleMania XI as a guest valet for villain Shawn Michaels, who faced heroic WWF Champion, Diesel. She left after the match with the victor, Diesel. McCarthy returned to World Wrestling Entertainment (WWE, formerly the WWF) on the August 2, 2008 "Saturday Night's Main Event XXXVI" to thank the fans for supporting Generation Rescue, an autism advocacy organization. In 1996, she landed a small part in the comedy "The Stupids". In 1997, McCarthy launched two shows. The first one was an MTV sketch comedy show "The Jenny McCarthy Show", which was sufficiently popular for NBC to sign her for an eponymous sitcom later that year, "Jenny". Also in 1997, she appeared on one of two covers for the September issue of "Playboy" (the other cover featured Pamela Anderson). McCarthy also released an autobiography: "Jen-X: Jenny McCarthy's Open Book".
