Three politicians were in a heated discussion as to which one was the best liar.
As the discussion was getting louder and louder the bartender suggested they have a liars contest.
After agreeing to the rules the first says, “I have never told a lie, “
The second indicated that he was not capable of telling a lie.
The third won the prize as he assured the bartender that, “The other two had told the exact truth. “
