RUSTY: No, I didn't. What's the punch line?
SAM: Punch line?
RUSTY: Yeah, everyone around here has been trying to tell a joke lately. What's the punch line?
SAM: There is no punch line.
RUSTY: How can you tell a joke without a punch line?
SAM: But I'm not telling a joke.
RUSTY: You got that right, Sam! It isn't funny without a punch line.
SAM: But I'm trying to tell you a story.
RUSTY: Right. And when you remember the punch line, be sure to not wake me from my nap.
SAM: But I'm trying to tell you a TRUE story!
RUSTY: A true story? You mean ...
SAM: Yep, two miniature horses ambled into a hospital in Chicago.
RUSTY: And they got arrested?
SAM: No, they were welcomed. They're therapy horses. They make the sick kids smile.
RUSTY: Oh, why didn't you say it's a true story?
SAM: I did. You can read it here - Horse trots into hospital: It's therapy, no joke.
