Notice that the joke in question could easily replace "President Barack Obama", "aides" and "ni**a" with "Tommyboi", "mate" and "ji**ie".
So essentially the joke is "black people are dumb".
Ahh, thanks. Now I didn't see it as that. I didn't see the face his black having any impact on the joke at all, I just didn't read that into it at all and saw word play on paypal with the word nigger tagged on to for effect or something and Obama use as he was all the rage at the time.
A bit like in SouthPark when they don't get why the flags wrong, because they just see a group of people as apposed to white people and black people.
Its still not funny at all though.
