“Prancercize,” creator Joanna Rohrback has teamed up with John Mayer, so get ready to “Romancercize.” In the video for Mayer’s new single “Paper Doll,” you get to read the lyrics to Mayer’s song as they flash across the screen. Lyrics that , according to some mean nasty haters out there, may be aimed at Mayer’s reported ex, Taylor Swift. Not only is the number “22″ mentioned (the title of one of Swift’s songs), but there’s another lyric, “Someone’s gonna paint you another sky,” that seems directly aimed at Swift’s line “You paint me a blue sky and go back and turn it to rain,” from her song, “Dear John.” That last song was allegedly aimed at Mayer and their messy breakup.
