Like this one:
"Paul [Martin] and I share a great vision for the future, two prosperous, independent nations joined together by the return of NHL hockey." (Laughter and applause.)
Yep, that was a terrific joke, delivered with perfect timing. Don't know if you got to watch the speech live, but I did. The President started out a little anxious, I think, so he slightly rushed the first part of the speech. But he got stronger and stronger as he relaxed. All in all, I think it was a marvelous speech, and our Dubya seemed quite happy at how it went.
