Columbia Law School professor Berit Berger uttered this one on the MSNBC show “The 11th Hour with Brian Williams”. She was discussing the pardon system and the Manafort case. This is a mashup of “turn (something) on its head” (to alter something in an unexpected way) and “throw it out the window” (forgotten, disregarded). “Turning” and “throwing” seems to have caused the mixup here. A big thanks to Frank King for hearing this one.
