As fun as it was to visit Disneyland and Disney California Adventure a few weeks ago, it wasn't the main reason for our trip to the west coast.

Neil Patrick Harris invited us to come out to Hollywood to be extras in an upcoming episode of the hit CBS sit-com, "How I Met Your Mother."

On this week's (very long) episode, we tell you the ENTIRE story.

We talk about what we saw, our interactions with the cast and crew and what it was like to be a "background extra" in MacLaren's Pub.
