If a comedian tells a joke that you find funny, you laugh. If he tells a joke you do not find funny, dont laugh. Or you could possibly go as far as groaning or rolling your eyes. Then you wait for his next joke; if thats funny, then you laugh. If its not, you dont laugh - or at very worst, you can leave quietly.
