The Boss, Wally and Dilbert sit together at a table. Wally says to the Boss, "I've been taking a self-paced online training course to sharpen my saw". The Boss replies, "What's the subject?" Wally answers, "I don't know." Frustrated with Wally's response, the Boss throws both arms in the air and yells, "How could you not know?" Wally answers, "What part of self-paced is confusing you?"
