Ha ha.

Here's one that made me smile - and before anyone starts on about racialism and stereotyping, the person who told it was a Jew -
A devout Orthodox Jew was walking along a cliff path, when he slipped and fell over the edge.  Frantically thrashing about, he managed to grab hold of a branch sticking out of the cliff face.  As he dangled there, he looked up to Heaven and prayed  "Please God, help me.  Help me - is there anybody there?"  And he heard a voice "This is the Lord, thy God.  Let go of the branch.  Trust me, let go of the branch. Hear the word of the Lord, let go of the branch".  And the man looked down at a drop of some hundreds of feet onto some very unpleasant looking rocks, and looking up to Heaven once again he said "Is there anybody else there?"
