The moment Liam Hemsworth takes off his pants and shirt and stands there in all his Grecian glory is tremendous. He's just gorgeous, and obviously worked out hard to achieve perfection (aided, I'm sure, by good lighting and a tan or body makeup).
While any scene involving the Hemsworth brothers semi-clad is always enjoyable (ahem...) one of my favorites is when Tilly rolls the fabric down the hill near the end. Her final line, "You never met the rubbish." ranks up there with "Fasten your seat belts, it's going to be a bumpy night." as a memorable movie quote... IMNSHO.
Edited to add: the scenes when William says "Gert, you look like someone out of a movie!" and Gloria Swanson in Sunset Boulevard pops up immediately after -- there's a message there but I'm not sure what it is... The whole bit at the theater is hilarious -- I'd love to see Sunset Boulevard with Molly.

Going off topic here, but for me the classic line is the opening one.
"I'm back ya baahstards"
Kate nailing the Australian accent and it's such an Aussie thing to say too. Brilliant!
