Wikipedia: Meta-joke
Meta-joke refers to several somewhat different, but related categories: self-referential jokes, jokes about jokes (also known as metahumor), and joke templates.
 
This kind of meta-joke is a joke in which a familiar class of jokes is part of the joke. Examples of meta-jokes:
 
. An Englishman, an Irishman and a Scotsman walk into a bar. The bartender turns to them, takes one look, and says, “What is this - some kind of joke?”
. A priest, a rabbi and a leprechaun walk into a bar. The leprechaun looks around and says, “Saints preserve us! I’m in the wrong joke!”
