Why is Percy literally shipped with EVERY character?

I mean I have heard of Percy being shipped with:

-Annabeth (Naturally)
-Piper
-Jason
-Nico
-Thalia
-Bianca
-Kronos
-Minotaur
-Artemis
-Athena
-Poseidon
-Hades
-Ethan
-Reyna
-Alabaster
-Zeus
-Stolls
-Rachel
-Apollo
-Hermes
-Octavian
-Luke
-Hephaestus
(I'm trying not to puke while picturing these)

I could go on all day. When I get bored sometime I just go on fanfiction.net and find the weirdest ships possible.

Sometimes I wish I hadn't. But I get a bored a lot....
