Thus begins a long-standing contrast between movie titles listed on the marque versus movie posters inside the theater. While "Monsters from the Drain" and "Cave Mom 2" line up (even though the second title is misspelled on the marque as "Cavemom's 2"), "The Empress Fights Back," "Prom Mom," "Buckets of Blood," and "Phat Camp" don't appear inside the theater at all. There IS a poster for "Dan Town.com" now playing that does not appear on the marque (which likely references series creator Dan Schneider).
At the Premiere Theater, Josh recommends Headless Honeymoon over Buckets of Blood as there's way more blood. Buckets of Blood is on the marquee, but Headless Honeymoon isn't.
The marquee calls out a movie as "Cavemom's 2," but the poster inside, and Josh's utterance of the title, shows that it's "Cave Mom 2,"
It is stated that Drake does not like ketchup on hot dogs; however, in The Wedding he is seen eating a hot dog with ketchup. It is likely that he may have changed his mind about not liking it. Then again, he was agreeing with everything Helen said at the time to stay on her good side.
Helen would have immediately fired Drake for selling Megan and her friends tickets to a PG-13 movie; however, she bought his lie about them being Norwegian, though he could have just told her Megan was his sister instead.
When Josh asks Drake where's his stereo, Drake says it's in Wisconsin, but Josh was trying to turn it on with the remote, so it would've seemed that Drake sold the stereo without the remote.
