Description[]
Barbara Diffy (née Speckle; born 2076) 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 ends up with something being wrong, because in 2121 they spray food out of a can. Before the show premiered, it was said she had an artificial body, but none of the episodes ever proved this. She forced Pim to be friends with Debbie even though Pim hated Debbie. Her maiden name is revealed in "Not So Great-Great-Grandpa". Barb is two years younger than Lloyd.
