divorce

"I want a divorce. My husband has been cheating on me."
"That's a serious accusation," said the judge.
"Do you have any evidence to substantiate your claim?"
"Yes. Just last night I saw him enter a movie theater with another woman."
"Who was this other woman?"
"I don't know. I never saw her before."
"Then why didn't you follow them into the theater and find out who she was."
"I would have," she explained,
"but the man I was with had already seen that picture!"
