Need help with ideas!

[Neo]

So most of you are probably familiar with the humor site cracked. They let most anyone write articles for them, so I thought I'd give it a shot. I've made five article pitches so far, one of which has made it to the editorial board. It was originally "6 scientific demonstrations that went horribly wrong," but they're having me change the focus to be people who were showing off in general and made fools of themselves.

These are the examples I have currently that I think will work:

A teacher that poured alcohol on an open flame and caught students on fire.
The DEA agent who shot himself in the foot during a safety demo.
The Navy pilots who dunked their helicopters in a lake while taking photos for facebook.

I need to find at least three more good examples of these types of failures. If you can help me out with ideas you will have my eternal gratitude. I can't use anymore examples involving teachers, and it can't be something generic like a drunk guy wrecking his motorcycle. They can be either youtube videos or stories from legitimate sources.
