There are various setups to this punchline. Here'
s one:
One day Johnny walked into the classroom, and the teacher said, 'Johnny, do you have your report
done?' He replied, 'no ma'am.' She said, 'if you don't have it
done by tomorrow then I'm going to make a call to your
parents.'
As Johnny is walking
home from school he looks to his left and sees two greyhounds racing,and one gets so far ahead of the other one that it just stops and the other one rams its
head right up its a**.
Johnny takes out a piece of
paper and writes it all down, saying to himself, 'This is going to be my report.'
The next day at school the teacher says, 'Johnny, do you have your report
done?' He says, 'sure do.' So he goes up to the front of the class and starts telling them what he saw. 'Yesterday I was walking
home from school when I saw these two greyhounds racing, and one rammed its
head right up the other's a**.' The teacher says, 'Johnny, we don't use the word 'a**' in the classroom, it's rectum.' Johnny said, "Rectum? Damn near killed 'Em."
Or this shorter version:
Teacher: So Johnny, how was your weekend?
Johnny: Horrible. A car hit my dog, right in the a**!
Teacher (correcting Johnny's language): Rectum.
Johnny: Wrecked 'em? Damn near killed 'em!
