The Opposite of Genius

Howard had some money to give away today so he played a new game created by Sal the Stockbroker. Sal called Gary the Retard and asked him to name the opposite of whatever Sal said. For example, if Sal said "up" Gary should say "down." A bunch of callers played but only one won, as Gary was very unpredictable with his answers. Here's a rundown of all of Gary's answers: 1. What is the opposite of Good? (Bad) 2. What is the opposite of clean? (Soap) 3. What is the opposite of dark? (Outside) 4. What is the opposite of loud? (Music) 5. What is the opposite of open? (Closed) 6. What is the opposite of poor? (Door) 7. What is the opposite of left? (Right) 8. What is the opposite of right? (Pen) 9. What is the opposite of small? (Girl) After hearing the "Soap" answer Artie jokingly said that he wished he was retarded. He said it's like you're always drunk. Howard was perplexed over why in the world Gary would answer "Girl" for small? Only one caller was correctly able to predict which answers Gary would or wouldn't know. The other two callers didn't even get one right.
