One day, a black man walked in to a cafe early in the morning
and noticed he is the only black person in there. As he
sat down he noticed a white man that sat down behind him
and this man said "Coloured people are not allowed in here!"
The black man replied:

"When i was born, i was black.

As I grew up, I was black.

When I am sick, I am black.

When I am in the sun, I'm black.

When I'm cold, I am black.

When I die, I'll gonna still be black. But you, sir...

When you were born, you were pink,

When you are sick, you turn green,

When you stay too loong under the sun, you turn red.

When you are cold, you get blue.

And when you die, you will be purple.

And yet you have the nerve to call me 'coloured'." - and the black man turned around and the white man walked away.
