Alright!   A youthful Bo Derek teaching boys gymnastics:  that aughta kick puberty right in. 

(& to think our boys had a learned old guy, who looked & taught like a palefaced Miyagi.)

Better for the dad's too, & some of the moms.  Yep, sounds to me like an all-round excellent choice. 

All joking aside:  I hope she fills the void, Andrea, for the kids.
