Why had this not been noticed sooner? Because Farrelly had painted a watch face on "Peter Jr" and had covertly wrapped him around his wrist!
[Many keen-eyed viewers noticed a melon "with a suspicious hole in the rind" in a scene in Me, Myself & Irene in which Jim Carrey lounges on his bed. The scene once had Renee Zellweger waking Carrey and noticing her photograph beside a "watermelon with a masturbatory hole in it." When test audiences groaned at the seedy scene, the Farrellys cut it, but accidentally left the melon in the film.]
