How many black people does it take to change a lightbulb? I dunno I couldn't see them in the dark
Would you like to explain why you brought this up?
I think it makes sense to figure out the color of their skin is too dark to see who does anything.
Black people can indeed be seen in the dark. It may be a bit harder to see them but the notion that they can be camouflaged in the dark is offensive to blacks. Some of them may even try dangerous things thinking this joke is true.
