About this MASH episode:
 MASH - "Showtime" is the 24th  episode of season one and it originally aired on March 25, 1973.
As a USO stand-up comic and female singing trio (backed by a small band) performs at the 4077th, and the performance is juxtaposed with clips containing the following: Henry’s wife back home gives birth to a son and the camp’s dentist receives his discharge papers and takes great pains to make sure he does not get injured before he sets off for home. Major Burns actually gets the upper hand over Hawkeye with three practical jokes. The first is when he sabotages the still, causing it to spray Hawkeye in the face with gin. The second involves the classic 'bucket-over-the-door' gag. The third and arguably craftier joke has Hawkeye attempting to use the shower, but is annoyed to learn that Frank has switched the showerheads to spray alternately whenever Pierce tries to use it.
