How can I remove ""None of the above"" from radio button options without making the field required?

FYI, I just came across this need and tried Dan's method and it worked great.  You basically just have to create a text-formula field, call it whatever you want, and put the below as the formula (make sure you check the Allow HTML box).

"<img src=\"/i/clear2x2.gif\" " &
"onload=\"javascript:if(typeof QBU=='undefined'){QBU={};$('label.NoneOfTheAbove').hide();}\">"

Then, just put that field somewhere on the form that has the radio buttons on it, and it will hide the "None of the Above" label.  Slick!
