Father/Son team Nicky Pfaff and the Immortal Grandpa discuss current events, past events, mohawks, and rubber band equality! Grandpa received his AB, MA, and PhD degrees in mathematics from UC Berkley. On a good day, he also has 98.6 degrees from Fahrenheit. His interests are like everybody else's--solving problems, collecting comic books, listening to Dr. Demento, and watching re-runs of Laurel & Hardy, Dragonball Z and Columbo. In our segment, "Letters to Mom," Grandpa reads one of the 200 letters he sent home to his mom during his college years, from 1955-1961. She kept them.
