Pot calling the kettle black
It happens when a person is guilty of the very thing of which they accuse another.
|“||"Oho!" said the pot to the kettle;
"You are dirty and ugly and black!
Sure no one would think you were metal,
Except when you're given a crack".
"Not so! not so!" kettle said to the pot;
A present-day example:
- Peter: "It is morally wrong to use animals for food or clothing".
- Bill: "But you are wearing a leather jacket and you have a roast beef sandwich in your hand! How can you say that using animals for food and clothing is wrong?" 
It is a fallacy because a person's actions or character do not affect the logic of the argument.
