Google search throws you a nice effect when you try searching "Do a Barrel Roll."

Should not it be "Does a Barrel Roll," assuming it's one Barrel (or barrel), or at least "Do a Barrels Roll"? (I assume it should be a question: "Does a barrel roll?" or "Do a barrels roll?")

EDIT: The problem is that I didn't know that "Do a barrel roll" wasn't a question. (Yes, it hadn't a question mark, but I felt that there was an historic reason not to add it.)

    Do barrels roll? Yes. Does a barrel roll? Only when the barrel is on its side. Do a barrel roll? OK, but I'm not even in a plane or playing Star Fox! – Zoot Nov 4 '11 at 21:13

This comes from the video game Star Fox 64.

In it, you fly around in a ship shooting stuff, and getting shot at by stuff. If you "do a barrel roll" (rotate your ship quickly along its axis of flight ie. rotate its roll), you are momentarily invincible.

Because of this, one of the other characters constantly contacts you over the radio to tell you to "DO A BARREL ROLL!" It became increasingly annoying and inappropriate, because by the end of the game I know when to do a friggin' barrel roll already!

Because it was repeated so often, the phrase became engrained in our minds. And because the game was so popular, the phrase soon became an Internet meme

I take the verb to be an imperative, so Do a Barrel Roll seems fine.

Because people would more likely search for "How can I do a barrel roll?" or "How to do a barrel roll?".

"Barrel Roll" is a noun phrase.

"Do" is the imperative form of the verb.

"Do a (Barrel Roll)" is the same as "Do a (dance)"
