The comics go to a convention. One brings a new guy. After supper, a comic stood and said, "142." Place laughed. Another stood and said, "147." The place broke up. The new guy wanted to try so he stood and said, "94." The place went silent. He was embarrassed and so he sat. He asked the guy next to him, "What did I do wrong?" Fellow said, "Some people just can't tell a joke."
