I know the punchline, but what's the joke?

[JamesH]

Ok, this hasn't really "bothered" me for years, but I've always wondered, when ever I hear the punchline, what is the rest of the joke? Is there a rest of the joke?

The punchline, you'll know it, is, "Recked 'em? Damn near killed 'em!"

Is this just a famous one liner that really isn't funny? Or is there actually a full version?

This is the punchline of complete joke:

Little Johnnie's teacher asked him how his weekend was.

"Horribly, a car hit my dog in the ass," he said.

She said, "Rectum."

"Wrecked him?" Johnnie said. "Damn near killed him!"

Yep, answer 1 got it. "That SB just ran over my dog's butt." "Young man, don't you know you shouldn't use language like that. You should refer to that part of your dogs anatomy, for instance, as its rectum." Wrecked him?! He danged near killed him?"

Fred's teacher asked him how his weekend was and Fred replied and said, "My dog got hit in the ass by a car."

Then the teacher says, "rectum, Fred, you mean rectum."

Then Fred says, "Wrecked 'em? Damn near killed 'em!"
