CNN has a story about a company that will, for a fee, give you official-looking notes explaining why you missed work:
Feeling like playing hooky, but nervous about getting caught? The Excused Absence Network has got your back.
For about $25, students and employees can buy excuse notes that appear to come from doctors or hospitals. Other options include a fake jury summons or an authentic-looking funeral service program complete with comforting poems and a list of pallbearers.
This sort of thing is why I don’t distinguish between excused/unexcused absences: Such a distinction asks me to judge who’s telling me the truth (or at least bothering to lie credibly). That’s not a role I want to play.
