Lisa was a scientist from the future, studying the effects of global warming. Note the shorts that were stunningly short. Zoinks! Maybe it was keeping her cool, but I can't say the same for people around her.
Lisa also volunteered to pass out the popsicle sticks. The sticks were little souvenirs with the date on them, but each one also has a unique quote written on them. Such as "Ready to Grow" or "Tired of the Game".
