Exactly.
Actually, Zero does not EVER laugh at himself. Not really. He mocks others. THAT is the only time I have heard him laugh...
Zer0 has shown no sense of humor that I have seen. He sounds snide at times and of course is full of himself. Better say this now because after Jan. 20 it might be considered a hate crime.
McCain was relaxed and rather funny on the show. I thought he showed some humor and came across as rather genuine. Probably helped himself a bit. I just wish there was more time.
