In the tune of 'Blackbird' by the Beatles...Madeline strumming on her guitar, " I have a brother...whose name is Pinkyyyyyyy. Yes his name is P.I.N.K.Y. Yes I tell you his name is Pinky....I have a brother, he is annoying and his name is Pinky because he likes Pink things...."
*******Cut to Sam, "MADELINE! STOP........Calling.........me..........PINKY!"******
Madeline, " I have a brother...whose name is Pinkyyyyyyy. Yes his name is P.I.N.K.Y. Yes I tell you his name is Pinky....I have a brother, he is annoying and his name is Pinky because he likes Pink things...."

Gotta love little sisters!
