"A comedian, she said, should be the sort of person, she said, that as soon as you look at them, she said, it makes you wanna laugh, she said..."

"A montage of hilarious features" - BBC

Above is the 'perfect comedy face', a blend of "179 facial aspects of 20 top comedians" created by scientists at the University of Stirling. They use it to argue that feminine features - a wide face, large eyes and softfeatures" are "the features most likely to mark male comedians out for success," as they imply a friendly, agreeable and cooperative nature. (BBC)

It would be quite interesting to see whether the same could be said for alternative comics, or those whose act is more confrontational; or whether the reverse is true for female comics (though finding the top 20 may be rather a difficult task). I'm drawing a blank when coming up with names, mainly because conducting the research with nothing more to go on than "wide face, large eyes and soft features", with no research team around you, is a decidely fluffy exercise.

It reminds me somewhat of this bit from Stewart Lee, here.
