John Greilick writes about these outtakes:

Possibly in honor of International Talk Like a Pirate Day, which is Tuesday, September 19th, these Notre Dame Marching Band members dressed up as scoundrels of the high seas to cheer the Irish during their game against Michigan last Saturday.

In 2002, Dave Barry wrote an article that was published in the Miami Herald in which he stated:

As the name suggests, this is a day on which everybody would talk like a pirate. Is that a great idea, or what? There are so many practical benefits that I can't even begin to list them all.

Baur and Summers came up with this idea a few years ago. They were playing racquetball, and, as so often happens, they began talking like pirates. And then it struck them: Why not have a day when EVERYBODY talks like a pirate? They decided that the logical day would be Sept. 19, because that -- as you are no doubt aware -- is Summers' ex-wife's birthday.
