When #1 ds was about 3 yo he had just learned the diff twixt guys and gals.
At that time he also thought mom and dad knew *everyone* in world.
DH was in the grocery store with him one day when sonny boy yelled out, "who's that guy, Daddy? Does he have a penis, too?"
DH is a very mild mannered guy and zipped as quickly as possible outta the produce aisle ;-)

DD#2 came to us at age 7yo from a foreign country. Today she is 15yo, but still has many english language quirks that delight us to no end, we call them *Tullisms*.
Some of my favs are :
Sad willow trees (weeping willows),and how she described to me that a doc had called to schedule a vaccination appt. for one of her bros. She told me the doctor had called for him to come him for his vaseline appointment. Nearly busted a gut over that one ;-)
