Mrs Goldberg is having a drink at the bar of her regular club when an oriental gentleman accidentally knocks over her drink.
"You damned Japanese!" yells Mrs Goldberg. "First you gave us Pearl Harbour, now this!"
"Hold on a minute. I'm not Japanese, I'm Chinese."
"Chinese, Japanese - so what's in a name?"
"And you Jews," replies the Chinese, "you can talk! You sank the Titanic!"
"We sank what?" asked the astonished Mrs Goldberg, "The Titanic was sunk by an iceberg!"
A normal phrase.
