What 2 tv characters had this conversation? Real names ,also. Okay?

Question

"Why don't you take that money and invest it in something? Why don't you do that?"
" Invest it in what?"
": There's wonderful land values outside of town. Now why don't you go out there someplace, look around, and buy yourself a lot?"
" A lot of what?"
"A lot! A lot of land!"
"Well fiddle, I can't afford to buy a lot of land. You probably could the way you've been a bilking and gouging... "
" Oh, hush up! I'm trying to help you, for heaven sakes. It don't cost a whole lot to buy a little lot."
"What do you mean it don't cost a whole lot to buy a little, or a whole lot to buy a lot, what do you mean?"
" Well, I mean,... a little lot of land!"
" But there ain't no such a thing. A little's a little, and a lot's a lot, there ain't no little lot, or lot of little, don't you see? Now you want that beer or don't you?"
"No I'm.. I'm all worn out."
" If you change your mind me and my friend will be over at the bar having a whole lot of little beers."

Answer 1

This was from Gunsmoke. The conversation was between Festus Haggen played by Ken Curtis and Doc Adams played by Milburn Stone.

Answer 2

I was going to say Festus and Matt Dillon, but sounds like the answerer before me researched it, mine would've been just a guess.
