In 1991, Sid Eudy helped bring Lauer to the World Wrestling Federation (WWF). He debuted as Harvey Wippleman, a Pee-Wee Herman-like character wearing a pin-striped suit with slacks cut at his shins, a red bow-tie, and a flat cap. He first managed Big Bully Busick. When Busick left the company and Slick turned face, Wippleman took over managing The Warlord. However, Wippleman's greatest acquisition was his real-life friend, Sid Justice. When Sid turned heel, working on a program with Hulk Hogan leading to Wrestlemania, Wippleman became Sid Justice's manager and became "Dr. Harvey Wippleman". Wippleman would begin carrying a doctor's bag to the ring containing medical equipment. After Sid's matches against jobbers, Wippleman would retrieve a stethoscope from his bag and listen to the defeated wrestler's hearts.
