'The Slutty Pumpkin' - Season 1, Episode 6
Robin and her new boyfriend Mike have a Halloween double date with Lily and Marshall, while Ted searches the rooftop party for a girl dressed as a pumpkin.
Air Date: October 24th 2005.
Lily: How about a Halloween double-date?
Robin: I don't know, we were kinda thinking about staying at home and dressing up as naked people.
Mike: Where's your costume, Gretel?
Robin: You thought I was...Oh, I was just kidding. I gotta stop making jokes in e-mails. It's so hard to convey tone.
Barney: Every Halloween, I bring a spare costume in case I strike out with the hottest girl at the party. That way I have a second chance to make a first impression. What's with the face?
Ted: It's half you're pathetic/ half I have to pee.
Ted: Come on, Barney, this is not about the odds, this is about believing. This girl, she represents something to me, I don't know, hope.
Barney: Wow. I did not understand a word you just said.
Robin: Well, what if I'm just a cold person? Tonight, Mike was willing to look like a complete idiot for me, but I couldn't be Gretel. Why can't I be Gretel?
Ted: Because you just haven't met the right Hansel yet. One day you're gonna meet a guy who's gonna make you want to look like a complete idiot.
Robin: How do you do this Ted? How do sit out here all night, in the cold, and still have faith that your pumpkin's going to show up?
Ted: Well, I'm pretty drunk. Look I know the odds are, the love of my life isn't going to magically walk through that door in a pumpkin costume at 2:43 in the morning. But it just seems as nice a spot as any to just ... you know, sit and wait.
Barney: Oh, you're dangerous, Maverick. Your ego's writing checks your body can't cash!
Barney: You are such a loser! I penguin-suited up for you!
Robin: How can a pumpkin costume be sexy?
Ted: It was carved in strategic places.
