I was reading the translations out of a Worst Case Scenario handbook. It's the travel version so they have all these neat little phrases you might need (like "Help me!" and "May I use your belt as a toruniquette?") My best friend is taking Japanese in school and thus I used the Japanese translations to quiz her. One I came to was written "Anata niwa oshiemasen."

After reading this to my friend she said, "okay my translation can't be right! But what I'm getting is "You are not delicious."

It actually means "I will not tell you."
