Marshall: That's Professor Lewis's office there.
Barney: Okay, let's take a look. Oh, yeah, it's a cougar all right. A prime specimen. See, you can identify a cougar by a few key characteristics. Start with the hair. The cougar keeps up with current hairstyles as a form of camouflage. The prey may not realize that he's engaged a cougar until he's already being dragged, helpless, back to her lair. Now, the blouse. The cougar displays maximum cleavage possible to captivate her prey. If you're watching them bounce, she's about to pounce. See the claws? Long and sharp, to ward off rival females... Or open alimony checks. Yeah, this one's a beaut. Okay, let the hunt begin.
