Lester, the Molester, comes from a family of well renown scientists. For years his parents tried and failed, to find a way to achieve permanent and eternal youth. But finally, after failure followed by failure, they found the perfect formula that would make anyone forever young.

But before they could publish their findings to the world, young, baby Lester accidentally set off an explosion in the lab, causing not only the loss of years of work but also the deaths of his very own parents.

Many years later, Lester, following in the footsteps of his parents; was finally able to duplicate his parents work. Or so he thought, instead of keeping him young, he found himself transformed back into his toddler stage with the mind of an adult.
