There's a scene in the 1980 film The Jazz Singer, in which Neil Diamond wears black face so he can sing in an African-American church.

It's all going well until one of the church-goers notices Neil's hands are white. Everyone is shocked. Then people start punching each other.

Last night I noticed the inside of a blueberry isn't exactly blue, so I peeled one.

This was surprising to me.

Then I started punching my family.
