"When you get the light in a comedy club, you know your time is up. Life doesn't always give you a signal," Carrey told ET. "Garry Shandling performed at the highest level on and offstage. He was an excellent man and he was more than ready for the Big Show."
Shandling died on Thursday at age 66. His publicist, Alan Neirob, confirmed to ET that the cause of death was an apparent heart attack.
Conan O'Brien also paid tribute to Shandling. During Thursday's episode of CONAN, the host took a moment to open up about how his friend helped him through a difficult time. See more in the video below.
