Marshall: Yeah, well, it was supposed to be, but my professor's like the toughest grader I've ever seen. She had like a bad divorce this summer and now she's taking it out on us. To tell you the truth, I think she just needs to get laid.
Barney: Really? Laid, you say?
Marshall: You wouldn't be into her. She's, like, in her late 40s.
Barney: She hot?
Marshall: Yeah, I guess she's kind of hot, yeah.
Barney: And she's looking for some action. Sounds to me like she could be a cougar.
Robin: A what?
Barney: A cougar. An older woman, usually in her 40s or 50s, single and on the prowl for a younger man.
Ted: What's a woman in her 60s or 70s? A turtle?
