I'm surprised Skivvy or one of the other Pyrates Royale hasn't chimed in, but they used to (and may still) lead The Pyrate Cheer:Pirate: "Give me an R!
Audience: R!Pirate: "Give me another R!"
Audience: R!Pirate: "Give me another R!"
Audience: R!Pirate: "What's that spell?"
All together: "Aarrrgh, aarrgh aarrgh!"Seems to work well with kids and childish adults...
