This is a full recording of a stand-up comedy performance by Stewart Lee. The comedian uses observational humor and satirical commentary, weaving personal anecdotes with broader societal critiques. The performance centers around observations on cultural reactions to 9/11, the absurdity of political statements, and the nature of comedy itself.
While the provided transcript doesn't contain a specific instance where Stewart Lee delivers an offensive joke and then explicitly states it's "just a joke" or "just banter," his entire performance is built around a meta-commentary on the nature of comedy and offense. He frequently uses irony and self-awareness to undercut potentially offensive statements. The act itself could be considered an extended exploration of this theme, even if he doesn't use those exact words in a single, self-contained segment. To definitively answer your question, a review of the actual video would be necessary, as the nuances of delivery and tone are not fully captured in the transcript.
