A kid called up his Mom from his college and asked her for some
money, because he was broke.
His Mother said, "Sure, sweetie. I will send you some money. You
also left your calculus book here when you visited 2 weeks ago.
Do you want me to send that up too?"
"Uhh, oh yeah, o.k." responded the kid.
So his Mom wrapped the book along with the checks up in a
package, kissed Dad goodbye, and went to the post office to mail
the money and the book. When she gets back, Dad asked, "Well how
much did you give the boy this time?"
"Oh, I wrote 2 checks, one for $20, and the other for $1,000 out
to him."
"That's $1020!!!" yelled Dad, "Are you crazy???"
"Don't worry hon," Mom said, kissed Dad on the on top of his bald
head, "I taped the $20 check to the cover of his book, but I put
the $1,000 one somewhere between the pages in chapter 19!"
