I used to work with this good looking, yet creepy guy.
I'd be at my desk minding my own business, and he would go around my desk and invade my personal space, with his dick rubbing up against my shoulder, just to say "hi" to me in the morning.
I just hated him.

Finally, he cornered me at the copy machine and felt up my blouse while saying "hi". Yes, he was literally saying, "hi" when he did this stuff.

This was before the Clarance Thomas/Anita Hill hearings, and sexual harrassment wasn't taken seriosuly yet. I just walked over to my desk, grabbed my things and left.
They figured it out, fired the asshole, and asked me to come back.
