I don't know whom this is actually making fun of -- if I were hiring, I'd consider the presence of a cover letter with my name on it to be of far more informational value than a resume typeset in LaTeX. The cover letter would actually show me that the person made some modicum of effort to apply to my company; the LaTeX wouldn't give me anything I wouldn't be able to tell from the rest of the applicant's resume. And there's no way it's worth more than "started own company".
