It was Sunday. Jack went to a barber's shop(理发店)to have his hair cut. But he was not happy with the result. While he was walking along the street, he(meet) his friend Bob.
"What happened to your hair?" Bob laughed and said.
"I hadbad day today! I didn't like my old hairstyle, I went to a new barber's shop. But this one seems worse than before. You know, I am going to a party tonight." Jack said (sad).
"Oh, that's really a problem. Now I'll tell you what(do) when you go into a barber's shop next time: Have a look all the barber's hair, find outhair looks worst, and then go straight to him. "
"Why?" Jack asked.
"Who cut that(man) hair? Surely another barber cut it. He couldn't cut it(he), could he? In this way you know he can't be the worst barber." Bob said.
