He is turning around a new leaf

My daughter said this one yesterday and immediately texted me (I have malaphor hunters everywhere).  This is a conflation of  “turning around” and “turn over a new leaf”, both meaning to change.  Here is a great example using the malaphor:

Oprah Winfrey has dropped 25 pounds on her new diet!! After launching her OWN network and a subsequent battle against low ratings Oprah packed on some pounds. This year however the media mogul is turning around a new leaf and hired a new chef.”
