Lisa Silver is an extremely popular cheerleader at Pearl Bailey High School. In the pilot episode, she and Steve briefly dated although Lisa wouldn't even kiss Steve as he is "repulsive".
Lisa is also in "1600 Candles" where she accepts Steve's prom invitation.
Lisa has two close friends, Amy and Janet Lewis in addition to hanging out with the popular crowd at school.
It is unknown if Steve still likes Lisa due to the events of "Escape from Pearl Bailey". As a result, she contracted the herpes simplex virus, suffering from an outbreak of blisters on her lips and around her mouth.
She is seen with Amy at the football tryouts in "Every Which Way But Lose" and in front of the school in "Daddy Queerest".
Lisa teases Steve and his friends about having sleepovers in "A Piñata Named Desire".
Lisa appears at a party hosted by Roger's persona of high school student Bing Cooper in "I Am the Walrus" and at another party in "License to Till".
She is seen leaving Miss Laine's class in "Steve and Snot's Test-Tubular Adventure". She can also been seen fighting for Fairy Tale Land in the dodgem' ride background at the Familyland Theme Park in "Familyland" and standing at the vigil for Steve in "News Glance With Genevieve Vavance".
She passes through the school hallway in "Scents and Sensei-bility" and attends Mertz' party for the cool kids in "The Unincludeds".
Lisa was voiced by Carmen Electra in the pilot and by Elizabeth Banks beginning in "1600 Candles".
