Don't let anybody in who can't do a cool handshake! They aren't allowed on principality. [wrong word, but closer than usual. He'll do the up highfive and then think a moment]

Okay, then it's gotta be like a buuuuncha backhand slaps downward to chest level-! Wham, bam, bam, wham! [this has to be intricate or it's not cool enough to bond over!]

Then a normal shake to cap that off! [just a good firm handshake, classic]
