Tonight, comedian Garry Shandling promotes his new DVD Not Just the Best of the Larry Sanders Show.

Jon then talks with Baghdad Bureau Chief Aasif Mandvi about the Baghdad walls in a segment called "Wall or Nothing". Finally, Lewis Black makes fun of several Earth Day television specials in "Back in Black".
