Luckily for Josh, a sexy and ambitious toy executive in the person of Elizabeth Perkins is happy to lend a hand.
Wait, Something's Not Right Here...
The words "illegal," "immoral" and "icky" spring immediately to mind. Remember, Josh made that wish to be "big" because he was sick of waiting around for puberty. We would give the writers the benefit of the doubt and assume it just slipped their minds that this was (mentally and emotionally) a pre-pubescent kid being seduced by a 30-something woman. Then again, it seems hard to miss when Josh's big love scene comes right after the scene where he celebrates his 13th birthday. With his 13-year-old best friend.
It's not like they're even trying to hide the fact that their seemingly grown-up protagonist is still a child. Hell, his childlike manner was what attracted Perkins in the first place, which just adds another little layer to the already creepy romance.
