Three goddesses were sitting in an old Indian temple. Their names were Truth (always telling the truth), Lie (always lying) and Wisdom (sometimes lying). A visitor asked the one on the left: “Who is sitting next to you?”
“Truth,” she answered.
Then he asked the one in the middle: “Who are you?”
Lastly, he asked the one on the right: “Who is your neighbor?”
“Lie,” she replied.
And then it became clear who is who.
