A black man walks into a bar with a parrot on his shoulder . The bartender asks 'Wow where did you get that from?'. The parrot replies 'From Africa, there's loads of them there!'.
Can you tell me why you said this?
Oh, how else you gonna get slaves from Africa?
Slavery has been banned for over 100 years. I do not think that we should still be making jokes about things like that. They are people, we do not treat humans like our property.
