Quote from Barney in Little Minnesota
Lily: For all the years Heather's been visiting New York, Ted's never let Barney meet her. Ted: And I never will. Every year when the Mosby family Christmas card shows up... [flashback to Ted and Barney standing next to a Christmas tree in the apartment in 2005:] Barney: [singing] Pulling down her pants Yanking off my own Underneath the mistletoe I'll make your sister moan Oh! Heather's hot, Heather's hot We'll go all the way... [flashback to Christmas 2006:] Barney: [singing] I wish I could see her naked I wish I could see her naked I wish I could see her naked And down on all fours. [flashback to Christmas 2007:] Barney: [singing] Ted has a little sister Gets hotter every day And if I ever meet her With her boobies I will play! Everybody! Sister, sister, sister! [off their looks] What? I can celebrate Hanukkah, too.
