Barney: No one... I mean no one... could get laid wearing these. [laughs] Challenge accepted. I, Barney Stinson, being of sound mind and amazing body, will wear these overalls until I have sex with a woman. [runs off]
Robin: I actually dated that guy.

Ted: [answers phone] Hello.
Mrs. Douglas: Hello, Ted Mosby?
Ted: Yep.
Mrs. Douglas: The window is open.
Ted: What?
Mrs. Douglas: The window is open.
Ted: [to Marshall and Robin] The window is open.
Marshall: What are you waiting for? Run, Ted, run!

Marshall: [writing] "Dear 60-year-old Marshall. You should be working somewhere that's making the world a better place, or at least trying to. No pressure, dude. I mean, sir. Also, if time travel is possible, maybe you could give me a little sign on Tuesday, December 8th at... 8:29 p.m."
[Marshall waits]
Lily: So, someone sent back these chicken wings, because they were too hot. And I'm like, "Too hot? Are you crazy?" So, free wings.
Marshall: [writes] "Old Man Marshall, as long as you're still married to Lily, you're doing just fine."
Wendy: Sir, this is on us. Sorry the wings were so hot.
Elderly Marshall: No, dear. It wasn't that they were too hot. It's just that I had wings earlier. Much earlier.
