Did you tell him to, "Relax! Don't worry! Have a homebrew!"? No, wait...that was in somebody else's book. ;-)
I would never advise John to relax, he might slip into a coma

He almost made me slip into a coma trying to listen to him at an early morning conference seminar once. No disrespect, he's a heck of a nice guy, but listening to John talk about alkalinity as related to beer color at 9 in the morning after having been drinking all night was a bad choice on my part.
