Can you replace the question mark with a number?

An Air Canada plane leaves Toronto's Pearson 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 seemed 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 Chinese.'

No rike Chinese?' asks the co-pilot, ‘why not?' ‘You people bombed Pearl Harbor, that's why!'

‘No, no', the co-pilot protests, ‘Chinese not bomb Peahl Hahbah! That Japanese, not Chinese.”

Japanese, Chinese, Vietnamese …doesn't matter, you're all alike!'

There's a few minutes of silence.

‘I no rike Jews!' the co-pilot suddenly announces.

‘Oh yeah, why not?' asks the captain.

‘Jews sink Titanic!' says the co-pilot.

‘What? You're insane! Jews didn't sink the Titanic!' exclaims the captain, ‘It was an iceberg!'

‘Iceberg, Goldberg, Greenberg, Rosenberg, …no mattah …all fukin same.’
