Mom: (Annoyed) I'm really busy and you need to know how hard I work all the house stuff!
Dad: (Pretending to hear nothing and reading newspaper)
Mom: Send the laundry!
Dad: Hhmmm.. (Saying nothing)
... Mom left to join her yoga friends
Son: What's wrong with Mom?
Dad: It's PMS..
Son: What's PMS, Dad?
Daughter: It's Pre-Menstruation Syndrome, Idiot!
Dad: No, It's PISSED AT MAN SYNDROME..
