Jack's, like, his own sexual harrassment seminar.

Training sessions:

Sexual Harrasment I:
-the basics

Sexual Harrassment II:
-Torchwood 3

Sexual Harrassment III:
-Captain Jack Harkness

Also, about half the booklets have 'what not to do' crossed out and replaced with 'who not to do' and a picture of Jack. He's blowing a kiss at the camera.

And naked.
