"Jesus, why are you doing the big arms thing?"
"Well, I don't know... I just thought I'd do a big arms thing, I don't know."
"Well, I'm going to do a big arms thing as well."
"Yeah, me too! I'll call that the big arms..."
"Look, we can't all do big arms! We'll look like a squadron of Spitfires, for fuck's sake! I'll do big arms and you just look at me and go, 'Ooh, he's doing big arms.'"
Somehow, this is even funnier when there is an actual squadron of Spitfires outside your office window flying around in formation.
