儿子说笑话

儿子经常给我重复一个他认为很好笑的笑话，我只能一次次地去配合他。

Mommy, mommy! Listen to me!
OK!
Do you know how to spell DOG?
O! I don't know! Do you know?
D-O-G!
Yeah, that is great!
Then do you know how to spell FOX?
Gee! You got me again! Can you?
D-O-G! Hahaha! That boy said D-O-G! Mommy! Is that funny?
Yeah, that is so funny! But how do you spell FOX then?
F-O-X! D-O-G says DOG!

儿子没有看过电影，有一次儿子在家玩SPELL，有朋友在，他爸就说了这个笑话，结果他贩来改编了。
