Dilbert arrives at home carrying a bowling ball in a case. Dilbert says to Dogbert, "I joined a bowling league." Dogbert's ears fly up in surprise and he says, "Yikes! We've become lower middle-class!" Dilbert says, "Don't be ridiculous. Bowling is good exercise. I'm doing it to build muscle tone." At the bowling alley, Dilbert sees three men who have one huge arm and one little arm. One of the men says, "Hey! 'Little Arm.'"
