Manny Pacquiao 'Imagines' With Will Ferrell

He boxes, he legislates, and yes, he sings. Manny Pacquiao, a frequent guest on 'Jimmy Kimmel Live,' returned to talk about his work as a Filipino congressman, his upcoming bout with Antonio Margarito, and to join Will Ferrell in song. Billed by Kimmel as a "special night for lovers of music, and lovers in general," the pair sang the John Lennon classic, 'Imagine.' Pacquiao is a no newbie when it comes to performing on Kimmel; his other renditions on earlier appearances include the ballads 'Sometimes When We Touch' and 'Nothing's Going to Change My Love for You.'
