"A Bike For Christmas" joke

A couple of weeks before Christmas, a little boy decided to write a letter to Santa. As he started, "Dear Santa... " he thought, "No, I'll go to a higher authority," and decided to direct his letter to Jesus instead.
"Dear Jesus,
If you get me a bike for Christmas, I will be good for two weeks."
"No, no, no! I know I can't be good for two weeks," he thought to himself.
So, he started his letter all over again...
"Dear Jesus,
If you get me a bike for Christmas, I will be good for one week."
"No, no, no! I know I can't be good for one week either," he thought to himself.
He quickly ran to the den, grabbed their small statue of Mary, and wrapped it up in a blanket.
Once more, he began his letter...
"Dear Jesus,
I have your mother... if you ever want to see her again... get me a bike for Christmas!"
