Barbara Diffy

Barbara "Barb" (née Speckle) Diffy is Phil and Pim's mom. She is very interested in how things work in this century. Unlike other mothers, though, Barbara seems to let her kids figure things out on their own. She loves to cook the old fashioned way--however, her food usually turns out a mess, because in 2121 they spray food out of a can, thus she has no cooking experience. Her maiden name is revealed in "Not So Great-Great-Grandpa"; her great-grandfather is Kyle Speckle. Barb is two years younger than Lloyd, and is kind, loving, and very intelligent.
