It's a reference to Howard's "Terryology" system of logic. The following quote is him justifying his belief that 1 times 1 equals 2:
"How can it equal one? If one times one equals one that means that two is of no value because one times itself has no effect. One times one equals two because the square root of four is two, so what's the square root of two? Should be one, but we're told it's two, and that cannot be."
