Image of a hand holding a small business card. Card reads:
Dr Crobar’s Lung Extensions Shh! Don't tell anyone I handed you this card
With extended lungs you can: • Scream longer • Breathe harder • Brag about extended lungs
This procedure is not legal but I will do it for you. Do not tell the police or my family
The picture of the business card in the OP is the same picture used in the site linked in the email (and in your post)
