Size of the boat?

Or how it moves through the ocean?

The ancient debate continues:

 The consensus appears to be that while the stereotype of black-big, white-medium, Asian-small penises may have a bit of truth in it on average, individual male members’ dimensions vary far more. (Women who are tempted to say they can confirm a definite difference between races should first ask themselves what sample size a scientific survey would need to be statistically credible, and whether they wish to declare themselves to be, in essence, highly seasoned Wanchai hookers.)

I’m going to have to remember that line-I can think of at least a couple of times when it might come in handy.
