A businessman enters a tavern, sits down at the bar, and orders a double martini on the rocks. After he finishes the drink, he peeks inside his shirt pocket, and then orders the bartender to prepare another double martini.
　　一个生意人走进一家酒馆，在吧台坐下，点了一杯加冰的双料martini。喝完，那生意人往自己衬衣的口袋里瞥了一眼，然后又让服务员把杯子满上。

After he finishes that, he again peeks inside his shirt pocket and orders the bartender to bring another double martini.
　　喝完，生意人又往自己衬衣的口袋里瞥了一眼，然后又让服务生帮他把杯子满上。

The bartender says, "Look, buddy, I'll bring ya' martinis all night long - but you gotta tell me why you look inside your shirt pocket before you order a refill."
　　这时酒馆的服务生说话了，“呃，老兄，我整个晚上给你倒martini都没有问题，但你得告诉我，你为什么在点下一杯酒前都要往自己衬衣的口袋里偷偷看那么一眼”。

The customer replies, "I'm peeking at a photo of my wife. When she starts to look good, I know it's time to go home."
　　生意人回答，“我看的是我老婆的一张照片。如果照片上的人开始变得好看起来，那就说明我喝得差不多了，该回家了。”
