(The episode started at the Coffee Shop, where Eileen was giving Mordecai and Rigby bags of their breakfast.)
Eileen: Here you go, two breakfasts to go. I put extra syrup in your sausage scrambler wrap, Rigby, just the way you like it.
Rigby: Sweet meat! (rubs his stomach) Aww, yeah!
Eileen: So what do you guys have planned for your day off?
Rigby: Hmm! Hmm! Two words, six syllables.
Mordecai and Rigby: Snow Tu-Tu-Tu-Tubing!
