Troy learned a valuable lesson on Community this week: it's not always a good thing to act like a magical elf-like man.

Indeed, "Contemporary Impressionists" stood in stark contrast to last week's return episode of this NBC sitcom. On "Urban Matrimony and the Sandwich Arts," Troy couldn't bear the notion of Abed as anything but an Inspector Spacetime-loving, alternate reality-living pal, someone perfectly content to exist in his own universe, consequences and the reactions of others be damned.

Here, though, after initially castigating his friends for suggesting it, Troy finally realized there's a difference between life inside and outside the Dreamatorium - and that difference sometimes looks an awful lot like French Stewart and threatens to break your legs.

It's simply been accepted for so long that Abed's use of pop culture quips and references is a harmless, humorous coping mechanism for his pained childhood, but there clearly are consequences for living in one's own reality at all times.

And even though Community is a sitcom at heart, it's also a sitcom that has heart, from Shirley and Andre's wedding just a week ago to Jeff's ongoing father issues. Incredibly, it can interweave a realistic, serious step in the friendship between Abed and Troy with celebrity lookalikes, Chang taking on a young security detail and Dean Pelton crying out in admiring pain at Jeff's aviator-themed shadow.

And, oh, those celebrity lookalikes!

I'm sorry, Gillian Jacobs, but I'll likely never look at you the same way. Not without seeing you walking backwards and talking in a high-pitched voice. And, as an avid viewer of The Soup, every reference to Ryan Seacrest simply slayed me, with Joel McHale simply taking his weekly, well-intentioned bashing of that do-everything host to a wider audience.

You're more handsome than the guy whose famous for being handsome. I would have been happy if Jeff were never served a helping of humble (apple) pie. The guy's swagger had a new swagger and I loved it.

Quick hits:

• Jamie Lee Curtis? Why not, right?!?
• For her sake, let's hope Renee Zelweggeer does not watch Community.
• Jim Rash's fellow Oscar winner Renee Zelweggeer, I should say!
• Note to Ryan Seacrest: stay away from Chang. He has heavy flashlights for people of your ilk.

As always, you can relive the very best in our updated section of Community quotes. Now, if you'll excuse me, I've got an odd hankering to watch A League of Their Own.
