We used an Adam Sandler song for the first dance.
I'll guess the obvious: Grow Old With You? If not that, I bet it was one of his Goat Boy bits or Lunch Lady Land!
Yep, that's the one. I think every waitress in the place came up to me individually within 15 minutes to ask what song it was, too.
Lunch Lady Land would have been cool for general music, though. Definitely.
EDIT: we tried to use super balls as our wedding favor but the restaurant refused to allow it at the last second... what could possibly happen in a room full of 150 drunk Irish people and 1000 super balls? Come on!
