Schwartz, Cohen, Ginsburg & Langenscheidt, four Jewish friends, decide they want to go into business together. Schwartz says, "OK ... I'll invest £100,000." Cohen says that he'll put in £200,000. Ginsburg says, "All right, I'll put in £150,000." Langenscheidt says, "I'll put in £600." Cohen says, "If I'm putting in £200,000, I'll be the President and CEO of the corporation, Ginsburg, for your £150,000, you can be Vice President, Schwartz, for your £100,000, you will be CFO and Langensheidt can be the Sexual Adviser." Puzzled, Langenscheidt asks, "What is a Sexual Adviser?" Cohen replies, "When we want your fucking advice, we'll ask for it"
