MAX: And yet, as soon as that dinner’s over and I start cleaning up, suddenly that’s when you’re starving.
LORELAI: What can I say – watching someone work makes me hungry. If I hadn’t stopped watching This Old House I’d be five hundred pounds right now.
This Old House is a highly popular home improvement television show which has aired since 1979, and is broadcast from Stamford, Connecticut. Presumably Lorelai started watching it after she bought a house of her own in Stars Hollow so she could learn how to do home repairs; she probably stopped watching it once she realised she could get Luke to do everything for her.
We last saw Max having his first date with Lorelai in Love and War and Snow. We only just now discover that they been dating happily ever since and are still together.
