One of Philip's biggest clients takes a liking to Will during a round of golf and soon decides to make Will his advisor.
The man is eccentric and Will does all he can to talk himself out of the job, but it doesn't work because the money is too good.
Philip comes to tell the man that back in January he had to spend his birthday sorting out a mess caused by the client, and that he was pulling the account. The man's horoscope predicted a Capricorn would bring him good luck and the account is saved.
Later, Vivian points out that Philip's birthday is January 30, which makes him and Aquarius rather than a Capricorn. Philip has no problem maintaining that he's a Capricorn if it will save the large account.
