It's Always Sunny in Philadelphia, Season 5

Charlie:
Well I guess my letter would be about how Frank and I aren't really making memories together anymore. And you know how when we don't make memories together that's a hurtful thing for me.

Dennis:
Okay. Uhh, you know let's just dive right in I'm not even going to try and suss out where you're going with that one.

Charlie:
Right. Um, number one, when was the last time we played Night Crawlers together, Frank?

Dennis:
Oh, uh, okay. Wha-what is that?

Charlie:
Well, its not about you... why don't you just right it down and then... ?

Dennis:
Yeah, but you said it... you said Night Crawlers. Now... now I feel like I can't... move past it. I gotta know what that is.

Charlie:
It... its no big deal, you know. If I were you I'd just write it down cause its not really a big deal.

Dennis:
What is it?

Charlie:
Its... what it sounds like.

Dennis:
What it sounds like is that you two crawl around like worms at night. That's what it sounds like.

Charlie:
This is not about you.
