This unexpected collaboration with The Lonely Island has him thinking he's writing a soundtrack song for the newest Pirates of the Caribbean film. It deteriorates and ramps up the CMoF fast when it turns out the hook/chorus he wrote for The Lonely Island's song doesn't match the group's original lyrics at all.
It gets worse when Bolton tries to make the power chorus fit to some of the other films he likes... including Erin Brockovich and Al Pacino's Scarface (1983). With Bolton dressing up as the lead character each time.
Only Michael Bolton could turn Tony Montana's grenade gun into a flamethrower.
No mention of him as Forrest Gump? It worked for this troper because he had recently seen the movie.
His interruption of the second verse with "Now back to the good part!" became Memetic Mutation immediately, helped greatly by his facial expression and the fact that his hat never appears at any other time in the video.
