Question: How I Met Your Mother prattle?

Answer: Real-life smartypants Danica McKellar's back in this season's fourth episode as Ted's first-season one-night stand you know, the one who climbed out of his fire escape the morning after. Well, she bumps into him at the bar and apologizes for shagging and running, and then proceeds to set her sights on him anew. But she'll find herself competing for his affections with an old sorority sister of hers although "competing" might not be the right word since I hear there's some serious threesome potential here.
