Mary Jane (Mary Jane Croft) warns Lucy (Lucille Ball) that she'll have a nervous breakdown if she doesn't stop working so hard. Meanwhile, comedian Bob Bailey (Hal March) and his trained monkey (Janos Prohaska) show up in Mr. Mooney's office prior to performing at the bank's benefit show. You guessed it: Lucy takes one look at the monkey and assumes that Mooney has "gone ape"--and when the monkey seemingly changes back to Mooney, and vice versa, over and over, it's time for a visit to a psychiatrist!
