a number of years ago...
i had 3 student buddies all called peter, all on the same course with me, we hung out together in and out of class.

for the first 10 minutes or so the name thing caused a little confusion (i'd shout "hey peter!" and they'd all turn round) but soon we hit upon a cunning scheme...

one of the peters was called peter greene, so he became green peter.

one of the peters was the palest, most wan looking fucker you ever saw (i'm sure he was actually a bit translucent), so he became white peter.

can you see where this is going?

the third peter was from ghana and was one of the blackest black men i have ever met, so he became, that's right, yes indeed, black peter.
(ironically he told us he was rather paler than his brothers so used to get picked on at school in ghana!!)

so one day we were trotting up the stairs to the 6th floor, the 3 peters side by side a few steps ahead, when i shouted after them "oy! peter!" and green peter looked round but it was black peter i wanted so i called "oy! BLACK peter!" and indeed black peter stopped. just at the same moment a voice behind me said "that's fucking outrageous that!" commenting on my perceived racism. to which black peter replied "what should he call me? WHITE peter?"

and a second one involving the same guy...

we were all sitting in the college refectory having lunch when some (white) arsehole bumped into the back of black peters chair causing him to spill his coffee. the arsehole says "sorry brother!" to which peter replies, after seeing the colour of the guy "i am not your brother. your cousin maybe. but not your brother!"
