It's been a long night, and now the girl has snuck into the bedroom and teased Tom about how stiff his shoulders are. He's totally grossed out, and he's all, "Whoa, that's weird. Is this the same guy I used to know back in the day? Yup, it's the guy who used to teach me how to play the guitar." Tom's like, "Dude, I'm so glad you're teasing me, because I've got some tricks up my sleeve. I'll show you how to do this." And so it goes.
