Stock gush over a major celebrity. If this is said by a minor character, expect them to become a Loony Fan (or Ascended Fanboy), though often it's a main character squeeing over someone else. "Number One Fan" is another common term.
Sometimes linked to a visual gag where the person saying it is unusually tall or tiny.
See also Ascended Fanboy and Straw Fan. If taken too far, it turns into an Abhorrent Admirer, or even worse, a Stalker with a Crush. When it's the hero, it is often said to an old, retired character — which can be a great shock to his own fans, who assumed that old man had to be insignificant.

I said, "Why, do I owe you money?" He said, "No"
I said, "Listen pal, do I know you? Have we ever met?
Why do you want my name on this little piece of paper?"

I don't know you but I love you,
Like my brother I love you,
Put your arms around me 'cos I love you"
I said, "Hey let's not rush things."

I even got the underground shit that you did with Scam

Rayne didn't like having Brittany around though, even more so since she tended to ignore any helpful advice Rayne gave when she tried to be nice.

It's not sure whether or not he's sincere about it, though, as later he turns out to be the one who tried to frame Velma for thefts she didn't commit - only because he was fed up with being second to her all the time.
