See that's just stolen, straight up. I've heard at least three comedians make that joke.

(I, of course, am joking about joke theft, but it is a riff on an existing joke)

I got this one a minute ago in response to this post:

> A man walks into a library, and asks the librarian if they have any books on paranoia.

> The librarian leans over and whispers in his ear "They're right behind you"

I thought that was pretty stellar, compared to what you'd get even a year ago.

Initially impressed. But Googling for that shows a lot of hits.

Absolutely, it's an old joke. But the fact that the thing even knew it was a joke and told it reasonably well... the bar is on the floor. (the one the guy in the joke walked into)

It's one of several canned jokes you get with a very high likelihood. Try a couple of times and be dismayed - you'll be getting the same three jokes over and over again. I'm fairly certain they were specifically tuned to return that. It takes special prompting to get it to write a new joke, and the results are typically disastrous / surreal.
