The entire opening is amazing, from their little spot in the ruins, to when he gets sucked up by Sin. I especially like the line "Listen to my story. This...may be our last chance."

Just pretty much everything from when you battle Seymour in Gagazet until you get to the airship.

The rescue scene in Bevelle.

In...guadosalam, I think...when Tidus calls the Macalania temple the Macarena temple, and Wakka corrects him. I laughed so hard when he responded with "AYE?!"

D'jose temple I think, when they're talking with Dona, and Tidus is hopping up and down like crazy in the background.

Tidus and Wakka wrestling in the background during a very serious scene in Mt. Gagazet.

Tidus staring at Lulu's chest with the binoculars on one of the boats.
