'How I Met Your Mother' Season 7, Episode 5 Recap - 'Field Trip'

So, Ted's big "Stand and Deliver" moment with his field trip for his Intro to Architecture students wasn't all that educational. That's okay, we still learned a bunch of stuff from last night's "How I Met Your Mother." For instance:

1. Dating your therapist is creepy

Robin's therapist, Kevin (Kal Penn returns!), tells her that he's going to Alaska and can't be her therapist any more. But when she runs into him at the diner, she discovers the real reason he ditched her: he thinks she's cute but it would be unethical to date her. They finally do, though, and it goes pretty well until it's time for Robin to "get her swerve on"... and it turns out to be kinda creepy.

But Robin has a solution: since Kevin got two hours of vulnerability out of Robin, along with her deepest thoughts and emotions, she just has to be his therapist for two hours and get the same out of him. It works. Aww.

2. The world is going to end

Marshall is concerned that his new boss, environmental lawyer Garrison Cootes, is going soft. His concerns are confirmed when Garrison accepts a $24,000 settlement from a multi-billion-dollar pharmaceutical company. But when Marshall confronts him about it, Cootes reveals the real reason: he knows it's too late to save the planet. So why not have some cake and enjoy ourselves?

But when Marshall sees the ultrasound of his and Lily's baby, he renews his vow to save the planet, even if he has to do it himself. Lucky for him, Garrison saves him from delivering more fish humor to the Big Pharma execs, and lays down the environmental law on them.

3. The "Ewok Line"

Barney (still in the ducky tie) makes a horrible discovery when "Star Wars" comes up during a conversation with Norah: she reveals that the only good thing about the Ewoks in "Return of the Jedi" is that we get to see some of them die. This nearly causes Barney to break up with her on the spot. Why? Not just because he loves Ewoks... it's because of the "Ewok Line."

You see, Barney has a theory... nay, a scientific fact: If you were born before May 25th, 1973, you were past the age of 10 when you first saw "Return of the Jedi" and, therefore, you were too old to like Ewoks. If you were born after, you were under the age of 10 and you loved the Ewoks because it reminded you of your teddy bear.

Norah hates Ewoks, therefore she must have lied about her age... she's not 29, she's actually 37. Barney spends the episode agonizing over this fact, but later admits to her that he doesn't care how old she is. Lucky thing he said that, too, because it turns out she just saw the movies last year.

Other notes and awesome things:

- Nice "Friday Night Lights" joke! Season two totally sucked

- "How do you know my mom?"

- "Baddest mother nature lover around"

- Edward James Olmos, not Jacob James Olmos

- Germans really do love Hasselhoff
