T-Rex: Here is everything I know about the number eighteen!

T-Rex: It is preceded by 17 positive integers!

T-Rex: It is then followed by infinity larger integers, and an even LARGER infinity of larger real numbers. Also I think 18 is the 18th number we ever discovered, but don't quote me on that. Probably it's in the first 100 though, easy.
T-Rex: Um.
T-Rex: I think that's it??

Utahraptor: Wow, look at this plebe with his paucity of 18 facts!
T-Rex: What?!

Utahraptor: 18 is the ONLY number whose sum of its individual digits (1 plus 8) is equal to itself divided by two. BAM. This means it's ALSO a Harshad number since it's divisible by the sum of its digits. BAM. It's divisible by 3, 6, and 9, and those add up to 18, so it's a semi-perfect number too. BAM BAM BAM.

Narrator: EARLIER:
T-Rex: Utahraptor, how will memorizing all these facts about 18 help you?
Off panel: One day, T-Rex, I'll get my moment.
T-Rex: 〚thinks〛 One day, self... I'll give it to him!!
