Maxwell Smart: The moment I suspected there was something wrong with this old scow, I immediately telephoned headquarters, and I happen to know that at this very minute seven coastguard cutters are converging on this boat. Would you believe it? Seven!
Mr. Big: I find that pretty hard to believe.
Maxwell Smart: Would you believe six?
Mr. Big: I don't think so.
Maxwell Smart: How about two cops in a rowboat?
