This excellent malaphor was uttered by a CNN reporter on the program New Day on 8/9/18.  The reporter was referring to Mueller, and his ongoing negotiations with Trump’s legal team with respect to an interview with Trump.  It’s a congruent conflation of “running the show” and “calling the shots”, both referring to someone who is in control of the situation.  “Show” and “shot” are both four letter words that have similar sounds, and I suspect the reason for the mental mix up.  A big thank you to Mike Kovacs for hearing this one and sending it in.
