Please repeat after me…Listen and Repeat.
The first time I heard this I was, naturally, in class. It was all I could do not to burst out laughing. Do you have enough WHAT?

Another fun thing? “Peanut butter” tends to sound a lot like “penis butter” because in Japanese, there is a “tsu” sound, so “peanut” becomes “peanuts”. Needless to say, I heard these two things in the same lesson. Whew.
