The nature of comedy is 'just do it.' But I think what's interesting about it is this joke has been around and why. And it's just saying what's wrong and how wrong can you be if you say it. ↗
Do it no matter what. If you believe in it, it is something very honorable. If somebody around you or your family does not understand it, then that's their problem. But if you do have a passion, an honest passion, just do it. ↗
We did a lot of that in drama school: intellectualising and maybe justifying your position. 'I am a thinking actor and I have thought this through' - well, just do it. I much prefer the doing aspect. ↗
