Hello, Robot Sister

Dad: Hey, sorry to wake you up, but your little brother wanted to talk to you

Brother: (in his best robot voice)  Hello, robot sister
(phone rustles)

Dad: (in the background) say more, mijo. Say more!!
(silence)
Well, sorry.  I thought he was going to say more or I wouldn't have called you.
(little brother is heard screaming for joy in the background)
