Back to original question - I saw the episodes and they were ok. Johnny was being alot nicer at being an interviewer than at being interviewed.
He basically walked around at celebrity events and messed with people. At, I think, the Sundance Film festival he walked directly into an ongoing interview between a regular TV reporter and Kevin Spacey & Christopher Walken. He complimented Walken but didn't recognise Kevin, who, in turn, didn't seem recognise him and appeared miffed at being ignored.
That was pretty much the theme - either the celebrities didn't know Johnny and tried to avoid this freaky-looking spaz, they knew him and ran away, or the knew him and didn't run away in which case they got insulted.
All in all a mediocre effort.
