TOS #8: Miri

This is an awesome episode in which it is suggested that the presence of Captain Kirk can accelerate the onset of puberty, in girls like this one, Miri:



Turns out she also has a crazy disease and might go postal at any time (become a woman). In order to keep her busy and keep her from knowing what's going on, the Captain asks her to sharpen a lot of pencils.






This works, and everyone lives happily ever after.
