Conan O'Brien continued his Legally Prohibited From Being Funny On Television Tour over the weekend, but fans at the Universal Studios show got a special treat ... Jim Carrey dressed as Superman!

The two comedians belted out an emotionally-charged Superman (It's Not Easy) by Five for Fighting.

Before Jim enters the Gibson Amphitheatre stage, Conan says to the crowd, "Luckily, a very good friend of mine understands how I feel....cause he knows it ain't easy being Superman."

Who knew Jim could rock tights like that? Hilarious!
