Yes, I've observed the same phenomenon among French-speaking comedians. Almost non of them are good-looking...
Except two of them (Arnaud Tsamère and Jeremy Ferrari if you want to Google them), and guess what? They're the least funny of all the French comedians, I've tried to watch their shows, but I had to stop 15 minutes because it was so painfully unfunny.
So how do they get by? 90% of their fans is female of course, they lack talent but their good looks (and godly NW1's) compensates for that.
Great French comedians like Dieudonné or Jean-Marie Bigard may not be good-looking, but their shows could make me die laughing. And of course, it's not surprising that they don't have as much female fans.
It's really women who glorify mediocre artists just because they have good looks. They'll also vote for a candidate just because they think he looks good.
Of course these good-looking artists with not much talent will quickly be forgotten, usually after their good looks fade.
