Dresden/Marcone, or gen if you feel like it writer

I want a fic where Harry sees Marcone being really bad at something. We know that Marcone defines badass. But say, he was really bad at flirting [you know people threw themselves at him so that he barely got any practice], or a terrible cook (even worse than Molly which Harry didn't think was possible), or can't sing worth a damn. Something.

The awesome that is Marcone needs a weakness other than his 'no children' rule which in all honestly just adds to his awesome.
