Young Frankenstein

(Young) Dr. Frankenstein lectures on brain anatomy. (0:05)

Dr. Frankenstein asks, "Is the sedative ready?" (0:53)

Frankenstein's assistant Inga injects the monster first in the gluteal area (0:56) and again later in the back (1:12)

Frankenstein observes, "If I could find a way to equalize the imbalance in his cerebrospinal fluid he'd be as right as rain." (1:24) Could this be an early reference to what we now call "chemical imbalance?"
