Your funniest friend might also be the one with the lowest moral standards according to a recent study from the Journal of Personality and Social Psychology.
"Although highly moral people are often viewed positively for displaying admirable character traits, they may also be disliked to the extent to which they are viewed as sanctimonious, prudish, or unrelatable," the researchers said.
"Highly moral individuals should be no less likely to engage in forms of humour that do not involve any moral violation, their avoidance of more off-colour jokes that challenge moral norms may lead them to be seen as less humorous overall."
So basically have high moral standards can often come at the cost of humour.
It's also important to note that this isn't necessarily a bad thing either, it takes all sorts of people to make the world go round!
