Funnier version?

John boy wanted me to tell you a joke today.  There is a story behind it.

One day he came in and said "hey Mom, What did one frog say to the other frog?"  I said "I don't know."  He said, "Time's fun when you're having flies."

That afternoon, we were walking in our neighborhood and I said, "Hey Tommy, want to hear the joke John boy told me earlier?"  He said yes, so I said,

"What did one frog say to the other frog?"  He said "I don't know."  I said "Time's fun when you're having frogs."

He gave me a blank stare while I was bent over laughing.  John boy just looked at me and said "you messed up the punch line Mom."  

Since then we have decided that my version is funnier.
