Two roaches were munching on garbage in an alley when one engages a discussion about a new restaurant.

"I was in that new restaurant across the street," said one. "It's so clean! The kitchen is spotless, and the floors are gleaming white. There is no dirt anywhere -- it's so sanitary（卫生的） that the whole place shines."

"Please," said the other roach frowning. "Not while I'm eating!"

两只蟑螂正在一条小巷的垃圾堆上大吃着，其中的一只谈起了它在一家新开张的餐馆里的经历。

“那时我在街对面的那家新餐馆里，”它说。“那里太干净了！厨房没有一点污渍，地面闪着白光。任何地方都没有垃圾。那里是如此干净，整个地方都在发光。”

“请不要在我吃东西的时候说这个好吗？”另一只蟑螂不悦地说。
