[jQuery] Passing vars to function

[jQuery] Passing vars to function

HI, I have a simples question, hope to get some answer...
Im having difficulty to pass vars to functions like:
$("#artigos_listagem li").mouseover(function(e){
                var orgBg = $(this).css('background');
                $(this).css({
                    background: "#ffffaa"
                });
            });
            $("#artigos_listagem li").mouseout(function(e){
                $(this).css({
                    background: orgBg
                });
            });
Like you can see, inside the second function Im trying to use the orgBg vars, and I would like to pass like .mouseout(function(e, otherVar){
hope you can help me, thanks!
