The only thing crazier than James Corden in this skit is the fact that all parties agreed to do this. Dr. Phil who is "ready to rock this bitch" came completely out of his professional shell to become the newest member of Good Charlotte. From the eyeliner to the tattoo'd sleeve on his arm, Dr. Phil went into full character. His singing skill? Well I'll let you be the judge of that but regardless this was one of the funniest performances Good Charlotte has easily given. If Corden really wanted to give the people the biggest collaboration ever he should've had Dr. Phil do a song with Bhad Bhabie. Maybe next time. See the full clip here.
