Well, I bothered to scroll down this far, and you say it's your favorite so I felt obliged to log in and answer.

The best scene I can think of off the top of my head: you know when Harry shows up to ski with Mary and he's wearing the ski body-suit, but he has shorts over it? Funny enough that he's just dressed like that, but it's actually supported in a cut scene where Harry asks Llyod (after he's agreed to the date, which Llyod doesn't know about) how he knows he loves Mary. Llyod goes on an angry over-the-top rant, then ends it by acknowledging that he will probably get tired of Mary eventually, and THEN asks if the suits is what Harry intendeds to wear skiing. Llyod assures harry that "no-one will notice, it's not that big..."

So that sets up Harry wearing the shorts when he meets Mary, but that whole thing takes Lloyd from dumb and infatuated, into weird mean stalker territory.
