All sorts of things can go wrong (and usually do) when you demo a product live on stage. Even the legendary Steve Jobs was no stranger to the occasional SNAFU, as demonstrated here. Jobs was giving a demonstration of the iTunes Store’s podcast listings, and explaining podcasts to Walt Mossberg and Kara Swisher at the D3 conference in 2005.

Unfortunately he didn’t preview the content before playing it live. The language is NSFW, but still incredibly funny.

More LOLs? Watch what happens when you give people an iPhone 4S and tell them it’s an iPhone 5.
