Get Well, Bono!

Bono, the leader singer of U2, broke his arm while riding his motorcycle last month and he has not been able to perform with his band since. At a recent concert, Bruce Springsteen and Chris Martin filled in for him with the rest of U2 (which is awesome in itself). As a result of his injury, he had to cancel U2's week-long residency on The Tonight Show. But don't worry. Higgins announced "Not U2" as a guest on the first night of the November 17-21 week and people like Mario Batali, Jim Gaffigan, and Kid Rock filled out the rest of the week in replacement. The best part, though, was when Jimmy donned an Irish cap and sang Desire with The Roots. He is so talented.
