worse entertainer or performer of all time??

I would like to try something new or at least get away from what TT or amp should I pick type of posting.I am wondering from many of my fellow Audiogoners what performer past and present made you say to yourself WHO TOLD THIS PERSON THEY HAD SERIOUS TALENT. My pick would be for the moment Jennifer Lopez. I just have no idea how in the world she got where she is today. I guess just good luck and the exceptance of mediocrity. Please this posting was not meant to insult anyones musical taste.
