Good Will Hunting/Headscratchers

• When Will was pissing off the first psychiatrist (the one that "putts from the rough") and the said psychiatrist was storming out of the room, Lambeau was seen flirting with a student by preaching Maths romantically. I assumed the scene was meant to invoke certain reactions from the audience on Lambeau's character, but what exactly? That he's a pretentious douche bag, or otherwise?
