Marshall: Scott, when I get down from here, you are going to be in big, big trouble, mister.
Scott: Come on, Mr. E. Didn't you ever cut loose when you were a kid?
Marshall: That's irrelevant. I mean, of course I did. One time, when my parents were out of town, my brothers and I set the basement on fire hosting an amateur wrestling exhibition. There were some theatrics.
Scott: See, you get me. I don't think of you as some dummy I trapped on the roof. I think of you more like, like my dad. Can we keep the party going for 30 more minutes, please?
Marshall: Okay, Scott.
Scott: Thanks, Pop.
Marshall: It's fine, kid just needed to blow off some steam. [watches Scott "dancing" with the blanket] No! Grandma Gunderson knitted that! Scott!

Ted: Well, lucky for us, someone at this table is skilled in the art of detection. Robin's upset. She and Kevin are having trouble. He cheated on her.
Lily: No way. Kevin's an honest, decent guy who never on his best day could pull a hotter chick than Robin.
Ted: Maybe Robin cheated on him. Maybe Robin is the dirty bird who slept with someone else.
Barney: I don't know, this pole-vaulting thing seems like a slam dunk to me.
Lily: Oh, it is so obvious. Barney. What is the name of that guy you worked with... Uh, Randy? It was Randy.
Ted: Wait a second. I just cracked this case. The little maple leaf onesie. It made her homesick. That's why she's so upset. She's not going home for Christmas. She wants me to invite her to Ohio.
Barney: [loudly] That's got to be it!
Lily: Either that or she slept with Barney.
[Ted and Lily laugh. Barney joins in with exaggerated cackling]

Lily: Oh, you must be Scott.
Scott: Oh, hello, ma'am. It's nice to finally see your face. Well, I'd better go hit those books.
Lily: Hold it right there, young man. This is for helping out my husband.
Scott: Wow, 50 bucks. Merry Christmas.
[Lily walks in and finds the house trashed. Marshall yells from the roof:]
Marshall: Lily!
