Well, Theodore captured Lugia!
Years ago, my cousins and I came up with this long song (that's in Finnish) about how Theodore, who is one of my cousins had a crush on Misty, and wanted to get the greatest water pokemon to impress her. Then one night he saw Lugia on the ocean and decided that was the pokemon he had to get. So he embarked on an epic journey to catch it, coming across powerful water pokemon, but never caught them, because he had decided on Lugia.
Eventually, after great adventures, he finally caught Lugia, but was disappointed to find out it wasn't water type.
So he let it go.
We kinda refer to the song when we mean something you're trying to do is stupid/inplausible/not worth the effort/based on false information.
Also this, that's from a tv-show:
"You're spoiling the Hitler house!"
"Well, sorry, but for me that makes it more fun!"
