A white guy and a black guy died and were on their way up to Heaven and they had to stop at the Pearly Gates before they could enter. So the Angel Gabriel was there waiting for them, and he told them that they had to do something before they could go anywhere.
He told the white guy to pull down his pants, so he did and Gabriel grabbed his dick and squeezed. It instantly melted. The white screamed in pain, and was sent downstairs.
Gabriel told the black guy to do the same, and he grabbed his dick and squeezed but nothing happened.
When Gabriel asked him why it didn't affect him, he said, "This is the type of chocolate that melts in your mouth and not in your hands".
