Cheating Liar

Two friends are at a bar talking about their marriages. One says, “I decided to file for a divorce.”

The other responded, “Why are you getting a divorce?”

The first one answered, “My wife is a cheating liar.”

“How do you know that?” said the first one.

“Well, a few days ago, my wife wasn’t home the entire night and in the morning she said she spent the night at her sister’s house.”

“So?” came the response.

“So, she’s lying. I spent the night at her sister’s house!” said the first.
