I received the following joke today in my email. It was in marathi so I will translate it for you.
A donkey climbs up a tree. He finds an elephant already perched upon its branches.
The elephant asks the donkey, "Hey donkey what are you doing on this tree?"
The donkey replies, "I came here to eat an apple."
The elephant says, "But donkey, this is a mango tree."
The donkey replies, "It's ok elephant, I brought my own apple."
