This was another funny episode that becomes more important as you watch the series. I think there is a clue (in a future episode) to to Ted future wife (who is NOT Robin).. It was funny how Barney goes with Ted and how the matchmaker see straight through him. You also see Ted can push things (to "Ted "them) when it comes to love. While the women was nice it just wasn't meant to be. The only part I didn't like was the match maker tried to put relationships to an exact science. It's something that I just don't agree with.
The second story with the Cock a mouse was funny too. It's something you appreciate it more when you see Season 6. I like that you never get to see the creature.
This was a very good episode and spoiler alert comes into play later in the season.
