"One Man Shy"

Yester-day, I read in The Monkees: The Day-by-Day Story that "One Man Shy" was broadcast on BBC-1 at 6:15 p.m. on 28 January 1967, and I realized that the title of the episode is a play on words.  By itself, the phrase means "lacking one man" or "missing one man," but in light of the episode's plot (Peter's difficulties in talking to Miss Cartwright), "shy" takes on the meaning of bashful or reserved and functions as a post-positive adjective.
