Five years ago today, comedy legend and Marvel Cinematic Universe baddie Garry Shandling passed away at age 66. During his career, Shandling did stand-up, wrote a feature film (What Planet Are You From?), and created and starred in not one but two genre-defining TV series with It's Garry Shandling's Show and The Larry Sanders Show. Early in his career, he wrote for shows like Sanford and Son and Welcome Back, Kotter. He also served for a time as Johnny Carson's permanent substitute on The Tonight Show -- a job he surrendered to Jay Leno when It's Garry Shandling's Show was proving too demanding for the performer to do both.
