For weeks, I’ve seen occasional mention of the Nats “Rickrolling” fans before home games, with a newish video that explains proper ballpark etiquette.

(“Rickrolling,” if you really don’t know, is something you can Google.)

Somehow, I hadn’t made it to a Nats game since Opening Day, but I was finally there on Sunday, intent on getting a video of the video.

As you can see, my skills at capturing video of video are not particularly well developed. But this should give you the basic idea. Here’s the chorus, if you don’t feel like watching:

Never be obscene;

Never throw-oh things;

Never use improper language.

Never interrupt a ball in play;

Never fight — no horseplay;

Or else you’ll be-ee-ee ejected.

You’ll note the chorus says nothing about running the bases to protest deforestation. Although it’s possible that was in one of the verses.

Anyhow, as mentioned, plenty of fans have noted this new addition to the Nats Park pregame menu. You can catch it around 24 minutes before the scheduled first pitch. If you want to make sure you don’t miss it, you can also watch about 10 minutes of scrolling promotional offers and updates. I recommend doing this on the Miller Lite Scoreboard Walk, where pregame beers cost $6. (Yes, they used to be $5 just last year.)
