Never laugh at your own jokes. I learnt that code of conduct very early on, in the dog-eat-dog suburban playgrounds. But when it comes to the finest people working in entertainment, that rule goes straight out the window. It seems we just can't ever get enough of when a comedian, actor or otherwise loses their straight face in 'the moment'. The veneer of character drops away for a brief second, and the real person within becomes wonderfully apparent.
Sometimes, it's funnier than it should be. Other times, it's funnier than the final cut. But, all the time, it brings the world of distant celebrity down to a much more natural and endearing level.
Here are just some of the best bloopers, out-takes and on-set shenanigans plucked from an endless ocean of gold - if your favourite ain't here, feel free to share the love.
10. Tim and Eric Awesome Show
Tim Heidecker, Eric Wareheim and Zac Galifinakis might just have to be my first choices for 'dream dinner party' guests. No Absolut allowed though.
