I think that's a great idea...it's funny and it's about something that will entertain you too (which is what profs hope) since it's about something you enjoy. It reminds me of "A Modest Proposal," which suggests that all babies be killed (but is of course, satire and thus completely ridiculous). The only thing is that some organizations (orthopedic groups maybe?) might have actual stats on facts such as how wearing high heels long-term really do damage your feet. Not to be a Debbie Downer and all.
