A plane leaves Los Angeles airport under the control of a Jewish captain. His co-pilot is Chinese. It's the first time they've flown together and an awkward silence between the two seems to indicate a mutual dislike.
Once they reach cruising altitude, the Jewish captain activates the auto-pilot, leans back in his seat, and mutters, "I don't like the Chinese."
"You don't like the Chinese?" asks the co-pilot, "Why not?"
"You people bombed Pearl Harbor, that's why!"
"No, no," the co-pilot protests, "The Chinese didn't bomb Pearl Harbor! That was the Japanese."
"Japanese, Chinese, Vietnamese...doesn't matter, you're all the same!"
There's a few minutes of silence.
"I don't like Jews!" the co-pilot suddenly announces.
"Why not?" asks the captain.
"The Jews sank the Titanic."
"Jews didn't sink the Titanic!" exclaims the captain, "It was an iceberg!"
"Iceberg, Goldberg, Greenberg, no matter...they're all same!"
