Two drunks were sitting in a bar talking.
One of them said,"Light travels from the sun to the earth at
186000 miles per second. That's really fast."
The second responded."I'm not surprised, It's downhill all the way. "
两个酒鬼
一日，两个坐在酒吧里的酒鬼聊起天来。
其中一位说：“光自太阳以每秒186000英里的速度传送至地球耶！速度真惊人！”
第二位酒鬼答道：“没啥好惊讶的，一路都是下坡嘛。”
