The episode's title is a reference to the Dr. Phil show.
Josh's complaint over Drake getting introduced first could extend beyond this one episode to the show title of "Drake and Josh" itself. (In recognition of equal importance of actors Drake Bell and Josh Peck to the series, their name orders vacillate in the opening credits between episodes, with Josh's name sometimes appearing first and sometimes Drake's.)
Drake Bell, Josh Peck and Gabrielle Carteris appeared in different TV shows with the main cast members of What I Like About You, Amanda Bynes and Jennie Garth. Drake Bell and Josh Peck starred with Amanda Bynes in The Amanda Show and Gabrielle Carteris starred with Jennie Garth in Beverly Hills, 90210.
It is stated that Drake may be a bad aimer when Josh states in the opening sequence that he pees near the toilet.
