- When a broker on Wall Street wins a new client with a big investment account, the broker sometimes will shout "Gekko!".
- A gekko is a small lizard found in the tropics. An animated version acts as advertising spokeslizard for Geico (gekko, Geico, get it?), a subsidiary of Warren Buffett's Berkshire Hathaway.
Gekko comes from Gordon Gekko, a fictional character from the 1987 movie Wall Street, played by actor Michael Douglas.
