He claimed he was flirting with the bank teller and passed her a joke note with a request for $50,000 with his name signed at the bottom. When he found out police were searching for him he turned himself in. As part of his probation, Lange attended the Connecticut School of Broadcasting from March to June 1987. This led to him pursuing a comedy career, after he was heavily influenced by Richard Lewis.

2. In 1995, he landed a role as one of the original cast members of FOX's sketch comedy show MADtv. Lange had previous sketch comedy experience with the improv troupe "Live on Tape". Lange later attributed his hiring to the fact that he fit the John Belushi mold that was popular in sketch comedy.

3. Comedian Norm Macdonald, impressed by Lange's work on Mad TV, offered him a part in the 1998 movie Dirty Work. Although Lange frequently jokes about the film's poor reception he credits Macdonald and director Bob Saget with rejuvenating his comedy career, leading to several more film appearances and a lucrative TV development deal.

4. Lange was a cast member on the shortlived The Norm Show, starring Norm Macdonald. After its cancellation, Lange would be selected from numerous guest comedians auditioning to replace Jackie Martling on The Howard Stern Show, beginning full time on October 29, 2001.
