Four surgeons perform a surgery on a missile in an operating room. The missile has its paneling opened up for access for the doctors.
It doesn't make sense that medical doctors would be performing surgery on an inanimate object like a missile; usually, these doctors perform surgeries on people.
Why are the doctors performing surgery on the missile?
Damn it, I'm a brain surgeon, not a rocket scientist!

A play on the term "rocket scientist" --- usually, this is used as a figurative expression to mean someone smart/qualified broadly, so to be "not" a rocket scientist would mean not smart or qualified. However, here, the person is actually quite smart and qualified --- they are a brain surgeon, and the expertise they are being called to use is literal rocket surgery. A brain surgeon is not a literal rocket scientist that can fix a rocket.
