I spent a bunch of time making a comedy short film on youtube. And the result was a really top notch video. Unfortunately, Nobody has seen it. And I haven't a clue on how to get people to see it. Any pointers?

try using tag , if its a funny video use tags like (funny video ,humor video ,fun video ) and also use these tags in description ,hope that will work

Share it with your Facebook friends?

it is nice for sharing this information on fourm and also we can share on face book.

use appropriate tags, share it in social networking sites like facebook. Have you tried posting it to some triffic exchange site?..

Promote the link of the video just as you promote any other link. Try facebook, twitter. If it's really funny it should go viral.
