I'm pretty sure the line is "Bozeman acknowledged." As for why someone of his stature would do something like this, he is a fan, he probably thought it would be a fun thing to do.Are you sure that was Kelsey Grammer? I always thought it was Michael Dorn (the admiral hailed both the Defiant and the Bozeman in that scene, so it could have been either Worf or Bateson)...besides, why would someone as famous as Grammer only contribute one word ("Acknowledged") to a film like this?
