Freefall does Shout-Out a lot.
Here’s the big list, in order by comic:
- Comic 5: The Savage Chicken's registry is 1071-CCN, a reversal to the USS Enterprise NCC-1701. Also in the same strip, we learn that the ship Florence was meant to join was 1071-CNN.
- 47: "When in trouble, when in doubt, run in circles, scream and shout!" The source is questioned, but Wikiquote traces the quote to an "anonymous U.S. military saying" (1929), and says that Herman Wouk's The Caine Mutiny (1952) spread the quote.
- As a science fiction comic, it's also possibly a shout out to Robert A. Heinlein who used the phrase more than once in his writing (Heinlein probably picked it up from his time as an officer in the US Navy, much as Wouk did).
- 74: "Will I be able to play Quake Nukem, Doomed Heretic In Castle Wolfenstein 3D on the ship's computer?"
- 79: Helix barks instead of speaking, and communicates that Sam fell down a ventilation shaft.
- 105: Sam feels the need… and Helix asks whether it is the need for speed.
- 125: Sam blamed the Noodle Incident on "that spiky haired boy with the stuffed tiger", a reference to Calvin and Hobbes.
- 184: Helix cares for a pair of rabbits that, unbeknownst to him, Florence intends to eat. He names them Bun-Bun (from Sluggy Freelance) and Kevin (from Kevin & Kell).
- 185: Helix's comment in the last panel refers to the fact that, in Kevin & Kell, Kell once ate Jerry Springer Spaniel.

- 350: While seeking shelter during a hurricane, Florence ends up quoting the opening monologue of The Twilight Zone (1959).
- 410: Florence deduces that, because she's not in an enchanted castle, it's a dog and not an animated mop (from Disney's Beauty and the Beast).
- 440: Sam and Helix enter a movie theater called Thimble Theater. It shows cartoons, because its name comes from Thimble Theater, the comic strip that introduced Popeye. Sam and Helix will watch a Godzilla film.
- 441 to 451: There are cameos from several other webcomics. The captions under each strip identify the characters and their source comics.
- When Rabbit Howls in 442, as well as referring to Kevin being a rabbit married to a wolf, is the title of a non-fiction book.
- Breakfast at Tiffany's in 445, as well as referring to Tiffany from The Suburban Jungle, is of course the title of a book and film.
- The monster movie is a parody of the Godzilla series. The method of defeating the monster in 449 seems to be a parody of Independence Day

- 568: "On the gripping hand" is a Motie idiom.
- 597: "We are the Bureaucracy. Resistance is futile. Your assets will be assimilated." (Almost but not quite the catchphrase of the Borg from Star Trek: The Next Generation.)
- 760: The ship's AI exposes Sam to danger by opening an external hatch, and responds "I'm afraid I can't do that" when Sam orders it to close it, inverting a scene from 2001: A Space Odyssey.
- 770: Stuck in an air vent, Sam tries to remember what happened to Winnie the Pooh when he got stuck — incorrectly remembering his fate.
- 818: The inspector calls Helix a "bubble bodied booby", which is nearly one of the insults Dr Smith used on the ship's robot in Lost in Space.

- Every strip from 1390 to 1476 features a cameo. The robot religious meeting has robots from just about every TV series or film with robots, including Robbie, a Cylon, ED-209 , Astro Boy, a Skutter, K9, and even Noo-Noo.
