Yeah, it’s sort of a package deal that is hard to convey on the boards. Needs the real-life impersonation.
You have to stand, slouch like a vulture, take off your sunglassess, tilt your head sideways, sigh, and say:
“(slowly) Baaaaah-ob… Tell me… how is it (preganant pause) that your blood was in her car? (quickly while leaning over suspects shoulder) You moved her body. Isn’t that right?”
The writers supply the dialogue, he supplies the delivery.
It’s nice that he’s so east to immitate though. A laugh-riot at parties.
