"Rex Goes To College" joke

A young man goes off to college, but about one-third of the way through the semester, he's foolishly squandered the money his parents had given him.
"Hmmmm," he wonders. "How am I going to go about getting more dough?" Then he gets and idea and phones his father.
"Dad, you won't believe the wonders that modern education is coming up with!" he says. "Why, they have a program here that will teach Rex how to talk!"
"That's amazing!" exclaims his father. "How do I get him in that program?"
"Just send him down here with $1000," the son says, "I'll get him into the course." So his father sends the dog and the $1000.
About two-thirds of the way through the semester, he again runs out of money. He calls his father again.
"So, how's Rex doing, son?" his father asks.
"Awesome, dad, he's talking up a storm," he says, "but you just won't believe this, they've had such good results with this program, that they've implemented a new one to teach the animals to READ!"
"READ!?" says his father. ""No kidding! What do I have to do to get him in that program?"
"Just send $2,500, I'll get him in the class," the son says. So the father sends the money.
At the end of the semester, the son finds he has a problem. When he gets home, his father is going to find out that the dog can neither talk nor read, so he shoots the dog. When he gets home, his father is all excited.
"Where's Rex?" asks his father. "I can't wait to hear him talk and listen to him read something!"
"Dad," the son says, "I have some pretty grim news. When I got out of the shower this morning, Rex was in the living room kicking back in the recliner, reading the morning paper, like he usually does. Then he turned to me and asked, 'So, is your dad still messin' around with that hot blonde who lives on Minute Street?'"
The father replies, "Damn! I sure hope you shot that lyin' dog!"
The son replies, "I sure did, Dad!"
