On February 24,1980, ten-year-old Linus was quite the lumphead, by saying his nine-year-old brother Luke had a square head and Luke repaid Linus by calling his head a rectangle head,and with that he crowned Linus as Linus lost his pompom snowhat. "Now you're a lumpheadin more ways than one,Linus!" exclaimed Luke,as a huge lump appeared on Linus' bare cold head.
