A businessman enters a tavern¹, sits down at the bar, and orders a double martini on the rocks. After he finishes the drink, he peeks² 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, buddy³, 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 peeking⁴ 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。”
