It's Always Sunny in Philadelphia, Season 10

Charlie:
Look, I'm just trying to come up with a system. We gotta have a system here, y'know?

Mac:
Wait, wait, wait, we do have a system for this! Paddy's Succession Plan, remember?

Dennis:
Oh shit, right. Yes, right! Paddy's Succession Plan! It was, like, a will we drew up to determine who would get each one of our shares in the very likely event of our untimely deaths.

Mac:
We drank, like, three bottles of tequila and then we started talking about our legacy and how important that was to us-

Charlie:
Gotta have a legacy.

Dee:
Oh, here we go. On a paper plate, huh?

Mac:
Yeah, read it, read it.

Dee:
"Paddy's Succession Plan - Paddy's Pub shall secure our legacy here, henceforth and forevermore, throughout the birthright of our firstborn kin." Who hit the pen here?

Dennis:
It makes sense, don't be a bitch- what it means is, every one of our shares gets passed down to our firstborn.

Mac:
Right! Right, our firstborn!

Dee:
The shares get passed down to the firstborn kin? We are the firstborn kin of Frank!

Charlie:
Well, hang on! That's not, like, an official document!

Dee:
Uh, well, you signed it in your blood.

Mac:
Oh. There it is: "Chrundle", written in blood.

Charlie:
Oh, yeah. I was going by Chrundle at the time, wasn't I-

Mac:
Nope. No, you were trying to write Charlie, and you wrote Chrundle.

Charlie:
No, I was going by Chrundle the Great.

Mac:
You came up with that after you miswrote it.
