Silly little thing that made me laugh out loud. A Final Fantasy forum might be able to appreciate this.
I was playing FFX, and entered a battle. Wakka said "I'll show you what I can do, Lu" or something like that, in a voice obviously showing his desperation to prove himself to her. Immediately after saying that he gets attacked and becomes confused. His turn was right after that and what does he do? Smacks Lulu with a Blitzball.
The timing was just so perfect I couldn't help but burst out laughing. There's no better way to prove yourself to someone than to smack them with a blitzball.
