Lisa Fary's earliest influences are Princess Leia, Rainbow Bright, Astronaut Barbie, and her 6th grade teacher, Ms. Palmer. She's angry that it's 2011 and she still doesn't have a hovercraft, but will accept a jetpack as consolation. That jetpack had better be pink with a rhinestone monogram.

LOL! My sister, who is 62 now, wrote an English paper in high school about how it feels to have big boobs. I wish I had that paper, it was funny as hell! And she got an A, of course–and those days were when your slip had to touch the ground when you went down on your knees–and they checked! I was sent home more than once for not having my shirt tucked in or not wearing a belt! My mom had the same problem with big boobs–but she was about 5′-2″!!! At least my sister is 5′-7″.
Your sister sounds awesome.
