Are you sure you want to learn about such stuff? ;-)

For this one you can look at what input \footnote usually allows:
   a) \footnote{some text}
   b) \footnote[mark]{some text}
So in the example I made \footnote a macro with one optional and one  
mandatory argument, which it then throws away.

Some footnote packages goes to great lengths to allow \verb within a  
footnote and then my quick fix would break down as soon as you took  
advantage of that feature. Then you could do something like

   \makeatletter
   \renewcommand\footnote[1][]{%
     \@ifnextchar\bgroup{%
       \def\@tempa{\egroup\setbox0=\box\voidb at x}%
       \setbox0\hbox\bgroup
       \bgroup\aftergroup\@tempa
       \let\@tempb = }{\@gobble}}%
   \makeatother
