Even though zombified Whitney and scandal-plagued Audrina didn't have much to teach us on last night's wisdom-packed episode of The Hills, Spencer, Heidi and Lauren blew our minds with life lessons we'll carry with us forever. And despite not saying anything that even remotely resemebled wisdom, it must be said that Justin Bobby, with his new haircut, has officially reignited our Bad Boy Crush phase. Intrepid Defamer Videographer™ Molly McAleer worked her magic to present the episode's most eye-opening moments, which we've broken down into three essential bits of knowledge:

1. How To Advance Your Career By Seducing The Boss! Without an annoying dandruff-headed fiance to keep her busy, Heidi is focused on her job as some kind of powerful publicity manager who rose through the assistant ranks by age 21 using one simple method: subtly let your male boss know you want to "get your hands in there" and "make yourself available" to them moments after uncrossing your legs.

2. Puppies Are Cutest When Their Eyes Match Yours! After frenemies Audrina and Lauren adopt a brand new trendy Boggle (that's half boxer, half beagle to those of you out there who aren't cool enough to like, know already) to never take care of, Lauren notes how awesome it is when your puppy's eyes are the same colour as yours! You know what else is awesome? The fact that this Boggle marks the third appearance of a puppy lovingly adored in the show's history, the first two having made their lovey dovey debuts briefly during the first season, never to be heard from or seen again. Are these poor things actor pets? Like Eddie on Frasier?

3. Guaranteed Way To Make Girls Leave A Room! Simple! First, repeat "La, la, la, la, la, la" in a flat monotone while simultaneously rolling your eyes. Second step? Be. Spencer. Pratt. In fact, scratch that. All one needs to do is Be. Spencer. Pratt.
