Since virtually the beginning of the series, Ted has been pining for his slutty pumpkin on Halloween. So on the ten year anniversary of their initial -- and only -- meeting, fate and a friendly guy at the costume rental shop intervened and Ted found himself at her door on 'How I Met Your Mother' (Mon., 8PM ET on CBS).

Katie Holmes took on the iconic role of the slutty pumpkin, where we quickly learned that she will definitely not be the mother -- never mind that we've already met the mother's ankle in another apartment. The chemistry between the two was just disastrous, but the romance of the story kept Ted hanging on way longer than he otherwise would.

When he did finally go to break it up, his mind knew what to do, but his mouth betrayed him and he told her he loved her instead. She sealed it with a kiss. Or did she? As we ultimately learned, her internal monologue was as uncomfortable as his. She was playing along for the same reason. And that kiss? That was so he wouldn't propose.

Sometimes the fantasy is best left where it is, because the reality simply can't live up to it.
