John grins full out now. "You got it, Doc," he says. "Figured it was at the back of that massive brain somewhere."

He surely hadn't expected Mac to have any idea what he was talking about, so he's a little surprised when he gets growled at, but he smiles again quickly and figures he'll just tell the truth. It's easier. "Chill, Mac, your blood pressure's gonna go higher than the Mir Space Station with a hair trigger like that. Read it in a book, just like I'm sure Daniel here did, isn't that right?" He winks at the Doctor laughingly.
