Joke that i heard. Might have further variants. ‘Difference between men and women’:
Woman spends all nite out with another guy. Come morning, husband asks where she’d been. She says with her girl friend. Husband calls 15 of her closest friends. All of them deny she was with them last nite.
Guy spends all nite out. Wife asks where he’d been. He says with his buddy. She calls 15 of his buddies. All 15 of them confirm he was with them, 3 of them say he is still there with them.
