Frog

The science teacher lecturing his class in biology said, "Now I'll show you

this frog in my pocket." He then reached into his pocket and pulled out a

chicken sandwich. He looked puzzled for a second, thought deeply, and said,

"That's funny. I distinctly¹ remember eating my lunch." 

青蛙

　　老师正在给学生上生物课：“现在，我将要给你们看我袋子里的这只青蛙。”接着，他把手伸进口袋，却拿出了一份鸡肉三文治。老师满脸困惑地看了一眼，沉思了一会儿，说道：“真奇怪。我明明记得我已经把午饭吃掉了。”
