Yeah, same goes for movies aswell as actors....like Will Ferral for instance, I don't think he's even the slightest bit funny but he still has a career and appears in movies (far too much IMO) ... so there must be some strange people about (with bad taste in humor) who find him funny and watch all his movies and make them blockbusters(when they're actually cr4p)
But away from there, you do find some people who think they are funny & that others feel they have to laugh along with them - when in fact they're quite boring really & you just want to yawn!
