A couple was on a journey. As the husband was driving, they saw a herd of cows and this was the conversation...
HUSBAND: Hahahaha, hey honey.
WIFE: What is it?
HUSBAND: Did you see those cows?
WIFE: Yes, what's wrong?
HUSBAND: They are your brothers and sisters.
WIFE: (she smiled) Yah... they are definitely my in-laws.
