John Cleese is one of the funniest humans ever to grace Earth. From Flying Circus to Fawlty Towers -- perhaps the funniest show ever made -- to Wanda, this man is the epitome of comedy. Logically, he doesn't disappoint in his replies to YouTube commenters.
They are simply hilarious, especially the part in which he talks about how truly stupid people can't really really be aware about how incredibly stupid they are. But, as nobody thinks he or she is stupid, does it mean we are all stupid? Probably.
