Freddie Mercury's Hearing

Listen here, you buffoon. You think this is clever? You posted this, and it is not. So here's the deal: "Hearing aid" is an actual product that people who have trouble hearing may use. The joke is that it sounds like "hearing aids", which is a type of disease. It is a pun. Freddie Mercury had AIDS, a real disease. The joke is not funny. Get a grip.
