Dress up as an 'escaped pfizer mRNA test subject'. You'll be sporting zombie makeup (to make you look sick) as well a some type of lab coat that indicates you escaped from a Pfizer testing lab. On the lab coat, you'll have a label (perhaps white duck tape) that reads '100% effective' crossed out and '95%' over it, then "90%" and so forth down to something like "-10%". You'll also have 9 band aids over your arm, or lab-coat to indicate all your injections. "Pfizer mRNA test subject XX2030" should be across the back of the lab coat.

With a nervous tick, you say such phrases as:

• "What do you mean you haven't got your 9th booster?!? My 9th booster only works if you've gotten your 9th booster"
• "Fauci gave me an ouchie" then you'll rub the arm OPPOSITE of the injection arm (just like Fauci did)
• "You know, it came from a bat" as you lick your lips like a psycho.

I think you can have a lot of fun with this costume.
