Reminds me of when I took an Asian friend deep sea fishing on a party boat off the Florida coast. Soon after we got on the boat some crotchety older woman kept shouting out "who brought the banana". My friend was getting visibly angry. Apparently "banana" is a term for Asians who were more North American than, in his case, Chinese...."yellow on the outside, white on the inside". Man was he miffed at this woman, until I pointed out the literal banana on the bench beside her and explained the whole "banana in the boat superstition"
