Some of the Japanese I had learned had quite an effect. One time, when the bus was taking a
long time to get started, some guy says, "Hey, Feynman! You know Japanese; tell 'em to get
going!"

I said, "Hayaku! Hayaku! Ikimasho! Ikimasho!"--which means, "Let's go! Let's go! Hurry!
Hurry!"

I realized my Japanese was out of control. I had learned these phrases from a military phrase
book, and they must have been very rude, because everyone at the hotel began to scurry like mice,
saying, "Yes, sir! Yes sir!" and the bus left right away.
