Sing a joke

I think it's to apply for a job in Mickey. I said there was a man who was stupid and didn't know anything. When I went to find Mickey to apply for a job, the supervisor asked him what your major was. The man said that he had no special skills, and the supervisor asked him if he could sing. He said he would sing for me, so he sang a delicious KFC life. . Of course, you can say that he went to KFC to sing M's advertising song.
