Andy Taylor: Yeah.
Barney Fife: Now, the second number... is... you just remember... lucky... seven.
Andy Taylor: Lucky seven.
Barney Fife: See? Now you got one and seven.
Andy Taylor: Yeah.
Barney Fife: Now, what's the third number? Seven. Now, that's easy to remember 'cause you just remembered seven, see?
Andy Taylor: [chuckles] Yeah, that's right. Yeah.
Barney Fife: Now, you got one, seven and seven.
Andy Taylor: One and... two sevens, yeah.
Barney Fife: Now, what's the last number? All right, here's how you remember that: What's one... from... seven?
Andy Taylor: Six.
Barney Fife: Six.
[they laugh]
Barney Fife: 1776.
Andy Taylor: Yeah, that's good!
Barney Fife: Yeah, it works out, too!
Andy Taylor: Wouldn't it be just as easy just to go ahead and remember 1776?
