A kid called up his mom from his college and asked her for some money, because he ran out of it.

Mom said, "'Sure, sweetie. I'll 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?"

"Uh, oh yeah, OK," responded the kid.

So 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?"
