When someones voice command menu on their phone says "Please say a command," at a non mother friendly moment everyone yells "Call Mom" in hopes that the phone will call the cell owner's mother.
(Student) - "Hey, Mom!"
(Teacher) - "Detention!!"
(Student) - "But its November 20th! (Call your teacher "mom") day!"
(Teacher) - "Im sorry, I must have been mistaken! No detention today!"
Person A: Hey, your mom called.
Person B: Yeah?
Person A: Yeah, she wants to know if she can borrow some batteries for her vibrator. (Or something equally disturbing)
