T-Rex: Alphabetical Order: arbitrary but useful! Famously, the number-one most useful arbitrary sequence you'll ever memorize!

T-Rex: These properties earn it an EASY four out of five stars!

T-Rex: Reverse Alphabetical: arbitrary but backwards, more often used for challenges or stunts than anything practical.
Dromiceiomimus: A decided step down from our previous contender garners this sequence a mere TWO out of a possible five stars.

Utahraptor: So what's left now?
T-Rex: Alphabetical Mod 5!
Utahraptor: Oh no.
T-Rex: Oh YES.

T-Rex: Alphabet Mod 5: every fifth letter, which is then removed from the set, repeated until no letters remain. Functionally useless, aesthetically unnerving, this godless combination of math and memory is utterly without grace OR utility. Zero stars.

T-Rex: Alphabet But Each Letterform Is Replaced By A Full Length Garfield Comic: it is a symptom of our fallen world and a fatal blow against Leibniz that we do not communicate through CLASSIC GARFS. An easy FIVE STARS; with perfection achieved, our exercise is concluded.
