!!Tropes:
* EverybodyPoops: A movie Bart got Dennis Leary in.
* MoodWhiplash "Night is scary. DAY IS AWESOME!"
* MyBelovedSmother: The B-plot has Marge learn not to be so smothering toward Bart.
* ShoutOut: It's not the first Australia [[TheSimpsonsS6E16BartVsAustralia hears it for Bart]].
* TookALevelInJerkass: Lisa learns her family was chasing a bird called a Scarlet Tanager and its migration pattern leads to [[spoiler: Machu Picchu, where Lisa had expressed interest in visiting earlier in the episode. She "conveniently" neglects to tell her family this so she can go on the trip she wants.]]
