(Nick, Kurt and Dale are attempting to sneak into Rex's house) Dale : Wait. Shit. What if he's in there? Kurt : Oh, yeah. How do we make sure he's not? Nick : (sarcastically) I don't know. Why don't you guys ring the doorbell while you're hot? Kurt : (taking sarcasm seriously) I love it. Smart. Nick : No. Don't. Don't, Kurt! (Kurt rings the doorbell, which rings 7 notes from Badfinger's "No Matter What"; Dale and Nick run and take cover) Dale : Oh, shit! Are you kidding?! Kurt : You know, it's pretty dark in there. I don't think anybody's here. (rings doorbell a second time) Nick : Don't...don't hit it again! Kurt : You hear that? Dale : I know that song. Kurt : Huh? What is that? Kurt : It's a song, right? Is it... (singing) No matter what you do... Nick : No, no. Dale and Kurt : (singing) I will always be with you... Dale : Who sings that? Kurt : Badfinger. Dale and Kurt : (singing) Doesn't matter what you do girl... Nick : (whispers) Quiet! Dale and Kurt : (singing, ignoring Nick) Ooh, girl with you... Nick : You nailed it. Dale and Kurt : (singing loudly, still ignoring Nick) Knock on this old gray wall! Nick : (whispering loudly) Shut the **** up!!
