I see London, I see France

Used to indicate humorously that one is able to see someone's underpants. A shortening of the childish rhyme "I see London, I see France, I see (someone's) underpants!" I bent over to pick up the pencil, and someone crowed behind me, "I see London, I see France!" A: "Ha ha! I see London, I see France!" B: "Oh, grow up, Jerry. So my underwear was showing, big deal." When I heard "I see London, I see France!", I spun around and demanded to know why Eddie was even looking there.
