Got Mommy's Milk

Dad and his toddler son walked up to
the counter at a fast food restaurant and ordered lunch.
They sat down at the table.  Dad handed his son a
drink.

Son:  "I don't want that. I want milk."
Dad:  "I'll have to go buy a milk then."
Son:  (Screaming)  "No!  I WANT MOMMY'S MILK!"

Pretty sure Mommy's Milk is not a fountain drink.
