This is one title I couldn't intuit (Usually looking at the tv.com title listing it's easy to identify which episode title refers to the episode I just watched.).
Barney: The only reason to wait a month for sex is if she's 17 years, 11 months old.
Oh, Barney, you so sleazy.
In "Matchmaker," Robin and Barney beg out of hanging out at Marshall+Lily's in a stakeout for the cockamouse (which, btw, dumb dumb name; "mouseroach" -- or "roachmouse" -- would have been my choice, though yes I imagine it was at least in part for comic effect on the writers' part) being of a similar mind about the ridiculousness of the whole thing, and I remember seeing that and thinking "Whoa, Barney and Robin pairing up, weird" 'cause I like Robin a lot and Barney not so much and so of course that comes under the "No you are not good enough for the character I like." As Barney says, though, they make a surprising amount of sense as a pairing.
"Best Prom Ever" isn't until 1.20 but we're already establishing Barney's "Hey, Robin, gay?" (Yes I appreciate tiny detail continuity.) And Robin's "No, I'm all about the dudes" statement totally doesn't negate canon bisexuality for her 'cause she was totally playing that girl -- though no I don't expect them to make her canonically bi.
And yes, I'm also trying to get a handle on Robin's character to write backstory fic for her.
Barney: (to Robin) You suited up!
I was really glad that the color came back (yeah recording over-the-air broadcast) for the cigar lounge. I loved her totally getting into it.
Robin: Well, it looks like it's gonna be just you and me.
Robin: (a bit surprised) Actually, I was talking to my martini.
Robin: What the hell are you doing?
Barney: I'm birthday suiting up!
Robin: No. I thought we're just hanging out as friends.
Barney: Oh, come on. You've been throwing yourself at me all night.
Robin: What? I did the opposite, I threw some other girl at you.
Barney: You invited me up to your apartment to play Battleship. Is that not an international recognized term for sex?
Barney (to Robin): Great, I hope you are happy, you sunk my battleship!
I was really surprised that Barney sacrificed a hot girl in the name of some bro loyalty, so I felt like the world was no longer askew when it turned out he wanted to lay Robin (though when she came back and saw he was mostly undressed I totally thought that was just part of his "Of course I cheat when I play Battleship" thing -- distract your opponent and all). And yup, Robin likes Ted. (Which does not preclude her and Ted being a good idea as a couple -- see me and every crush ever, for example.)
[Barney: Ted can't drink -- 'cause he's pregnant -- 'cause he's the girl.]
Robin: Come on, Ted can't be pregnant....you need to have sex to get pregnant.
Ooh, good one.
I'm not sure why the gender stereotyping around Ted in this situation bothered me less than similar ones do in other situations. Maybe it was just subsumed by the broader issue and also was only one of a number of plot threads in this episode so I just didn't have enough time to really think about it?
