Play of the Day: In This Corner... Mitt Romney?

The late-night favorite and erstwhile candidate is lacing up the gloves for charity.

Late-night television hosts marked St. Patrick's Day Tuesday by wearing green and joking about the holiday's American traditions. The Tonight Show's Jimmy Fallon connected the holiday to Hillary Clinton's latest honor, while both Conan O'Brien and The Late Show's David Letterman joked about alcohol consumption and the Secret Service's most recent scandal.

The big news Tuesday was that former Massachusetts governor and late-night favorite Mitt Romney announced he will face former heavyweight champion Evander Holyfield in a charity boxing match. Nearly everyone took shots at Romney, with Fallon's staff producing several slogans for the match and Late Night's Seth Meyers referencing the pounding Romney received in the 2012 election.
