You see this skit all the time truncated at the end of the original joke. But the shortened version doesn't do Louis' comedic genius full credit. He finishes original gag and then walks to his stool. "Well, it didn't really happen." Audience laughs. Pauses, picks up water bottle, takes a swig. Audience laughs and claps. "This is what really happened, I'm not going to lie to you again." He ADMITS to the audience that he just lied to them! You get to see how his mind work. He tells the audience how his mind works. "We're really the same people, it's kind of hard to lose an argument when rhe other person is you too." A comedian telling an audience how his mind works...Admitting to his audience that he lied because, "It's as true as anything that really did happen." "Anybody somebody says something to me I just decide what they said anyway." Rare, rare, rare, that.
