Dr. Lewis Zimmerman and The Doctor in “Unfinished Business”

Emergency Medical Hotheads; Extremely Marginal Housecalls; that's what everyone used to call the Mark I's until they were bounced out of the medical corps. I tried to have them decommissioned, but Starfleet, in its infinite wisdom, overruled me and reassigned them all to work waste transfer barges. That's where you'd be, too, if you hadn't been lost in the Delta Quadrant. Do you know how humiliating it is to have 675 Mark I's out there scrubbing plasma conduits, all with my face?

The Doctor

I'm sure they're doing a fine job.
