The premise of the Squirting 101 series is to gather some guys (in this case, "college students") to get women to squirt under Braun's tutelage. The results, we are told, are often hilarious, sometimes requiring Braun to step in with his Lloyd's of London-insured hands.
No, Braun doesn't step in on his hands.
I'd like to think, though, that this late in the series Braun might have developed a curmudgeonly Walter Matthau-style persona, so that when he has to demonstrate yet again his squirting prowess he says things like, "God Damn It! How many times do I have to show you?" shuffling in with his Budweiser and racing form.
