At one of my previous jobs, one of our major clients was Heyman Corporation. I was VNC'ed into one of their machines from my site, on the phone with the female sitting at that terminal, and going through a quick explanation about how to use MSIE. So, up came IE.
Me: Now, let's go to the Heyman company home page.
Me [typing]: [link|http://www.heyman.com/|http://www.heyman.com/]
MSIE: Dutifully pulls up the porn site I just entered.
Me: Uhhhh, shit. Whoops. Sorry 'bout that.

Thankfully, she had a sense of humor. :)
