Is being funny important? Not particularly, however it's nice when people make others laugh. I think it is important to be interesting, or at least have some depth to you, boring people are well boring and that's boring.
I like to imagine I'm very interesting and funny, I've been told I am, I don't know. My sense of humour is dry and dark but it would seem everyone's into that nowaday, I'm also very sarcastic which people seem to enjoy, some people have accused me of "attention seeking" but I'd dispute that I'm just incredibly interesting and people are jealous that their eyes are pulled to me because I always have something witty to say!
