Little Johnny and Susie Smith are only 10 years old, but they just know
that they are in love. One day they decide that they want to get married.
So Johnny goes to Susie's father to ask him for her hand.

Johnny bravely walks up to him and says "Mr. Smith, Me and Susie are in
love and I want to ask you for her hand in marriage."

Thinking that this was the cutest thing, Mr. Smith replies, "Well Johnny,
you are only 10. Where will you two live?" So without even taking a moment
to think about it, Johnny replies "In Susie's room. It's bigger than mine and we can both fit there nicely."

Still thinking this is just adorable, Mr. Smith says with a huge grin,
"Okay then how will you live? You're not old enough to get a job. You'll
need to support Susie." So again Johnny instantly replies, "Our allowance.
Susie makes 5 bucks a week and I make 10 bucks a week. That's about 60
bucks a month. That should do us just fine."

By this time Mr. Smith is a little shocked that Johnny has put so much
thought into this. So, he thinks for a moment trying to come up with
something that Johnny won't have an answer to. After a second, Mr. Smith
says, "Well Johnny, it seems like you have got everything all figured out.
I just have one more question for you. What will you do if the two of you
should have little ones of your own?"

Johnny just shrugs his shoulders and says
"Well, I have to admit, we've been lucky so far."

That has to be one of the best Little Johnny Jokes I've heard so far!
