My brother-in-law just got some huge collector's box of all the Harry Potter movies and collector things, so naturally we've been talking about Harry Potter stuff. And it occurred to me that calling him "Hairy Potter" might make a fun ad for Rogaine. So Harry Potter could say he used to be a "Baldie-mort" like Voldemort until he used Rogaine and became "Hairy Potter"! And it was Baldie-mort Voldemort's jealousy about Hairy Potter's new hair that caused him to attack Harry, leaving the lightning bolt on his forehead. For it wasn't a death curse, but a curse on Harry's new hair that Voldemort attacked Harry with. But Rogaine is so powerful, not even Voldemort's baldness spells can work against its hair-growing power! (And this would help to explain why it is that Lord Voldemort is always so mean to everyone: he's mad because he's bald, and he wants to punish everyone else for having nice hair.)
And then if this ad sells lots more Rogaine, then it will be time to get Cousin It to endorse Rogaine too! After all, how else do you suppose Cousin It was able to grow all that hair?
