A black guy, a Mexican, and a white guy find a magic genie lamp

They rub the lamp and a genie appears and said he'd grant them all one wish. The black guy wishes that all blacks can go back to Africa and be together and the black disappears. The Mexican wishes the same that all Mexicans can be together in Mexico and disappears. The genie turns to the white guy and ask what he wishes for. The white guy replies and says "So all the blacks and the Mexicans are gone?" "I think I'll just have a coke."
