After a visit to the eye doctor leaves Lucy's vision hopelessly blurred for the rest of the day, she decides to go through a jitterbug number at an audition at Ricky's club.

Lucy concocts a delicious salad dressing, and Fred tells her she ought to sell it.

The problem: they've priced the product so cheaply that it will cost them rather than make them money.
