Bill Clinton On Bono Imitation: 'I Must Be Really Easy To Make Fun Of'

Turns out Bono is not just a globe-trotting rockstar and activist, he's a pretty good comedian too.

The U2 frontman decided to have a little fun before a panel discussion at the annual Clinton Global Initiative gathering in New York on Tuesday - offering up an unexpected and hilarious impersonation of former President Bill Clinton.

Capturing Clinton's signature Arkansas twang, Bono delivered a faux Clinton monologue: "When I first met Bono, he walked into the Oval Office and actually I thought he was a member of his own road crew. He wasn't dressed right. Actually, I felt like the rock star on that occasion."

A visibly amused Clinton finally appeared on stage, smiled and said, "I must be really easy to make fun of."

Bono appeared at the event - a meeting of world leaders, philanthropists, executives and others - as part of a panel, moderated by Clinton, titled "Mobilizing for Impact."

He sat alongside Christine Lagarde, managing director of the International Monetary Fund, and Sheryl Sandberg, chief operating officer of Facebook, among others.

Though the event deals with weighty issues - from global health problems to the challenges facing developing countries - former President Clinton has been injecting some humor into the proceedings.
