Garry Shandling was practicing his comedy routine on classmates at Tucson's Palo Verde High School in the mid-1960s.
He turned his high school comedy schtick into a 30-year career that included long stretches on "The Tonight Show with Johnny Carson" and two cable shows - "It's Garry Shandling's Show" on Showtime from 1986 to 1990 and "The Larry Sanders Show" on HBO from 1992 to 1998.
