Everybody knows Bono -- the U2 singer is one of the most famous people in the world, let alone one of the most famous rock stars -- but do you know his real name? No, he wasn't born with a single moniker for a name (big shocker). Instead, Paul David Hewson is the name on his birth certificate. The nickname Bono supposedly came from a hearing aid shop called Bono Vox in the band's hometown of Dublin -- that's Latin for "good voice."
