This is one of the only two TV episodes that do not end with a closing iris. The other episode is Double Whammy Part I.
This marks Russell's most painful and torturous death to date.
The title of this episode is part of the phrase "Out of idle curiosity", which means to want to know something for no specific reason.
The ship slamming into the iceberg head-on and sinking with everyone on board is a reference to the Titanic. Also, Lumpy looking for icebergs, ringing a bell, and The Mole quickly changing directions similar to the Titanic movie.
Sniffles retrieving the Idol and taking it to a museum could be a reference to Indiana Jones. The description for this episode titles Sniffles as "Indiana Sniffles".
Sniffles moving objects, like a bench and a soda machine, to block the door of the museum is a reference to The Blues Brothers.
Lumpy's death is similar to Toothy's death in Eye Candy. Both involves the eyes and brain coming out.
Flippy's helmet shelf from Easy For You to Sleigh appears in the museum when Sniffles is knocking artifacts into the crack.
When this episode aired along with Home Is Where the Hurt Is and Aw, Shucks! on YouTube, the alternate title for the trio was "Nine Lives". Lumpy, Giggles and The Mole appear in all three episodes. Giggles and The Mole die in all three episodes while Lumpy dies twice.
