it's pretty clear based on chris rock affirming it when louie says "so i'm a ******, basically'.
and yeah the joke backfired in the long run. another one of those "in the circle" jokes that takes on a different shape when heard by those outside of it. that's why he refuses to do it anymore, as he says at the end of the clip.
No, it's not really clear
. He did a horrible job explaining that that was the context if that's truly where he was going. To be honest though Gervais was really the worst thing about the clip.
and told him he can't find humor in that.

at this thread doing numbers.
How so?
