Presenting Pr0n.

I read Jacinta's post and have to agree with the statements she made.
I'm a red blooded male with crazy hormones running around my body like the next person, yet I know there is a time and a place for such things.

Let's put it in clear context. "Pr0n has no place in a technical conference presentation."

One wouldn't show pr0n related images to their own grandmother or a stranger in the street.
Use this 'stranger in the street' or 'my own grandmother' as a general guide if you are unsure.

If you feel the need to resort to showing such images, you need to ask why.
Is your presentation that dull you need to distract your audience?
Are your presentation skills that poor you need to resort to cheap stunts to keep your audience interested?
Is your knowledge on the given topic limited and needs attention to be misdirected away from the main discussion point?
Are you sure all your audience is of legal age? Being a technical conference doesn't mean there aren't minors present. Keep this in mind.
As a parent, I would be outraged if my teenage child attended such a conference to be subjected to pornographic images.

Playing the 'pr0n card' in a presentation shows a lack of maturity and disregard for your audiences intelligence.
It really isn't 'witty' at all and quite offensive.

Feel free to use humour in your presentation to liven it up, but keep it on a neutral topic and not one that is controversial.
Remember - your presentation is supposed to educate people to your point of view. You won't do this if it polarises your audience!

You would expect a backlash to your presentation if it contained anti-semitic or a white supremacist suggestions... expect the same with anything controversial.

If in doubt, why not run your presentation prior to the conference via the organisers. It's much easier cleaning up the slides prior to the presentation rather than the egg you'll have on your face.
