How can i disable ETags? And Should I?

Hello smart and talented members (hopefully I have won you over), I was wondering how I could possibly disable Etags? I tried putting this in htaccess:

Header unset ETag
FileETag None

But it just didin’t work. YSlow still tells me that my ETags need to be properly configured. Did I do someting wrong? Is it worth trying to fix this? This is for an html page with 3 images that repeatedly get requested over and over again.

Thank you very much for your input.

May the Pork be With you, always.
