In looking over AFI's list of top 100 movie quotes I realized that one of the phrases I say to Boyo most often- "Are you talking to me? Are YOU talking to me?" is directly from Travis Bickle's mouth overlayed with my own motherly treacle.
Motopop and I have also adopted the seemingly benign "Shuggie" as a nickname for Boyo in his happy state. This also has dark roots- one of the many disturbing/wonderful segments of Wonder Showzen.
I am hoping that the Brothers Grimm and the composers of Ring Around the Rosie didn't damage children too much since I can't quite stop entertaining myself by embedding the adult material I am used to into baby talk.
