A man is walking along a street and falls down a deep hole.
A doctor walks past and the man shouts up “Hey, I've fallen down this hole, please will you help me out?” The doctor writes the man a prescription, throws it down into the hole for him and walks on.
A priest walks past and the man shouts up “Hey, I've fallen down this hole, please will you help me out?” The priest blesses the man with a prayer and walks on.
A mentor walks past and the man shouts up “Hey, I've fallen down this hole, please will you help me out?”. The mentor immediately jumps into the hole and the man says “Are you crazy? Now we're both stuck down here!
The mentor turns to the man and says “Yes, but I've been down here before, and I know the way out”.
