please tell me.. what was the song name and singer name about episode wooo... like a r&b style ?

I really liked this episode, but it wasn't my favourite though, I still prefere 'Intervention'.
I loved the parts when Robin is talking to Lily and then Marshall shows up and figures out what they're talking about....that was awesome!
I also loved the part when Ted draws something (and we think it's the building) and then Barney describes it like: 'Ted, this is amazing! The detail, the shadind, the playfulness of the lines...this is exactly the way Princess Lea would look like topeless'
I LOVE this show, keep on the great work!

I done see why everyone loves this episode... I liked it but I think the best episode was intervention...

Robin- Dear Marshall,

I do not like that stupid hat,
I want to beat it with a bat.
Or maybe stab it with a fork,
It makes you look like such a dork.

HaHaHa

I agree with JOE that maybe we saw the mother in last night's episode. I don't particularly remember the girl JOE's talking about, but I think maybe Jillian, the head woo girl might turn out to be the mother. I think Jillian might be the girl JOE's talking about and it's obvious there's something there because she wanted to have a 3some with him and her friend who is secretly in love with her.

I think we might have seen the "mother" last night. The girl who was looking for Ted was also the one who mentioned "I dont think I will ever be a mom." in her woo. She has dark hair and looks alot like the girl whom Ted bumped into last season at the club where he found the umbrella. I dont think Old ted said anything because he hasnt "met" her yet he has just been near her and dosnt know it.

Let me add my voice to those caling this the best ep of the season. This was one of my favorite episodes ever. It just made me laugh.

By far the best episode of the season. I feel that this episode is the first one of the fourth season that compares with the first three seasons.

Also, like Joel said, loved when Barney checked out Robin's ass, although I percieved it as a move every guy who's trails a group would do when he sees a hot girl.

did anybody else notice that we finally found out what Barney was doing for work? At least somehow.

However, I kinda liked this episode. It really had some very great moments (like the "Fire Marshall" worde play ;)) or the discussion at the beginning:

Barney: "This is the last moment of Marshall and me in competition for the title of Ted's best friend."
Ted: "Marshall is my best friend."
Barney: "Exactly - it's a tie!"

And it was good to see something about Ted's architectual work, we didn't see that in a while. Also funny to see Bilson again. And the SVEN group was really weird.

Anyone else missing Robin on Metro News One?

Oh, crap. I meant to say "collective." That's what late night typing gets you. Fixed it.

I liked the fact that the SVEN Collective was bored with the conference call and decided to break into push-ups.

A few good moments and entertaining in general, but a bit stale. Not the best (by far), but not really the worst either....

(by the way, the push-ups scene was just OK...just wanted to correct Joel on the Collected/Collective thing!) :)
