It's the stuff Maxim subscribers' dreams are made of: ER's Busy Philipps has been cast on How I Met Your Mother as the hottie who may or may not end up in the sack with Ted... and his hit-and-run fling, Trudy (Danica McKellar, the Wonder Years cutie, thankfully all grown up).

As you may recall me telling you in a recent Ask Ausiello, in the Oct. 15 episode, Trudy is ready to go another round with Ted, but a new rival has already staked her claim on him - Trudy's old college frienemy, to be played by Philipps. So things could get heated in one of two ways: There could be name-calling and hair-pulling or clothes-ripping and sheets-tangling. (Either way, Ted's one lucky mother.)

Though Philipps is likely to fit right in with the How crowd, don't expect her to stick around beyond this pre-sweeps installment. Ted's pal Lily gives the sexpot the big thumbs-down after realizing that she's the shopper who ruined her shopping trip by walking off with a pair of coveted boots.

So what do you think, folks? Will CBS really let Ted have his cake... and Danica McKellar's and Busy Philipps', too? Take a cold shower, then discuss amongst yourselves.
