Thinking back on it though, I'm pretty sure mine went something like this:
Hey there buckaroo and buckaroo-ettes, as we sit here on this graduation day many of us have come to the realization that the days of roping miniature rocking-horse type bulls in the halls are over. It's time for the big rodeo of life. Many of us don't know what the future holds, but it's time to cowboy up, take that bitch by the horns and ride that sucker for all she's worth. We're talkin' the full 8 seconds baby. Now, go out there and git 'er done. Yeeeeee haaaaawwww!!!
At least that's what it looks like I'm saying in this picture*:

*I don't know who took this picture, I'm pretty sure it was my friend's mom, but I love how they didn't bother to try and move a few inches to the side in order to miss the back of someone's head.
