What exactly is she smiling about? Now we have a concrete answer: having her seven strategically placed touch sensors fondled with implied consent. Along with potentiometers in her nipples and photosensors in her eyes (she is watching you), Lisa lives up to her name. If left untouched for long enough, Lisa will indiscriminately moan at strange passersby who catch her eye, hoping to attract their grabby grease fingers. You're embarrassing yourself, girlfriend! Like a human woman, you can only please her by correctly guessing and activating sensors in a completely randomized, predetermined sequence that changes as soon as you figure it out.
