Sure, rival Conan O’Brien allowed himself one solid wisecrack during his own show: “The Olympics start airing tonight on NBC. It’s very cool. That’s right: NBC has the Olympics. It’s a big deal. NBC will finally get to show somebody who is okay with passing the torch.”

From singers like Justin Timberlake and Josh Groban to comedians Whoopi Goldberg and even competitor (and onetime critic) Jimmy Kimmel, it seemed everyone had plenty of praise for the nice guy of late night.
