Dogbert sits at a desk under a sign that says, "Tax Preparation $5.00." A man enters the office and says, "I need some help . . ." Dogbert says, "Sit down." The man says, "I always fooled around during math classes. Now I can't do my own taxes." Dogbert looks at the form and says, "We can prattle about your inadequacies later." Dogbert says as he fills out the form, "I'll do your taxes and talk at the same time so you really feel dumb." Dogbert continues, "Hmm . . . Simply multiply the standard deviation of the cosine of your depreciation and integrate the resulting polynomial . . . There." Dogbert continues, "According to this, you owe your tax preparer an additional two thousand dollars." A pile of money sits on Dogbert's desk. Dogbert says to the reader, "Confusion - it works for the IRS and it can work for you."
