When Gracie hands Jim his false ID, she says, "Here we go, Mr. Dimas." This presumably refers to Jim's nonexistent "friend" Gus Dimas in Season 3's "Imaginary Friend".
When the T-Rex skeleton collapses, the pieces sound as if they are made from polystyrene plastic instead of solid rock like real fossils. This suggests the museum has an artificial display skeleton, but the imitation bones were really created so that the actors could lift and handle the immense pieces.
When Cheryl and Dana go to the movies, they reveal that the movie stars Matthew McConaughey. Two months before this episode aired, Matthew McConaughey's hit movie "We Are Marshall" opened. Kimberly Williams-Paisley played McConaughey's wife in that movie.
Cheryl: You know what, over here they have prehistoric clothing.
Dana: Aaa... just like in your closet.
Jim: You broke this thing!
Andy: Me? All I did was take a picture.
Jim You used the flash! That's why they say: "Never use the flash in museum, you're not allowed to!"
Kyle: Doesn't that sign say: "Do not touch?"
Jim: Can you read yet?
Kyle: Not really.
Jim: It says: "Wet paint."
Kyle: There weren't any caveman when dinosaurs were alive.
Jim: Well... that's because the T-Rex ate them all, honey.
ABC repeated this episode on April 11, 2007.
There's seems to be an episode missing in the line-up continuity because in the previous episode Ryan was still stuck in Djibouti and wasn't aware he had a son yet.
ABC originally scheduled to air this episode on February 21, 2007.
At the end of the episode when Jim is leaving the museum, he is jumping around exactly like John Belushi did in the 1978 movie "Animal House" when he is spying on the sorority house.
