If the former coach had been Beaver Cleaver and had promised Mrs. Donaldson that he would mow her lawn for 50 cents and he had the mower out ready to start when Mr. Jones said,
“Hi Beaver. I see you have your mower out. I’ll pay you to mow my lawn.”
“I’d love to Mr. Jones but I promised Mrs. Donaldson I would mow her lawn and she’s paying me 50 cents.”
“I’ll tell you what, if you mow my lawn instead, I will pay you a dollar!”
So, forced to make the most difficult decision of his life, Beav sees his dad and says, “Dad, I promised Mrs. Donaldson is mow her lawn for 50 cents but Mr. Jones came by and said he would pay me a dollar if I mowed his instead and I only have time to mow one!”
What would Ward tell The Beav to do? He’d say, “Well, Theadore, didn’t you make a promise to Mrs. Donaldson?”
Well, gee, yeah, I guess I did, and that promise had very specific conditions which I met. Mrs Donaldson agreed to those terms too, so I guess she's accountable for the agreement we made. I get it dad! I need to keep my promise insofar as Mrs Donaldson required!”
“Good boy Beaver! Don't forget the lesson about ****ty contracts.”
