Spaceman Spiff blasts across the galaxy. Miss Wormwood asks Calvin to demonstrate the next problem. A Zok death sloop appears and fries Spiff's stabilizers. He hurls out of control toward his doom. Calvin writes the math problem on the chalkboard. The situation is desperate. What can our hero do? He downshifts his spacecraft and...stalls. Calvin writes a bunch of numbers and lines on the board. The class bell rings. Oh, darn, out of time. Spaceman Spiff once again beats all odds to save the day.
