I think anyone who buys a pen worths thousands of dollars is a little bit mentally retarded.
You can stab people with it, stick up your jacksy, or even one's urethra, plug holes in aircraft fuselages to prevent depressurisation and use it to deliver children if there's no hot water and towels to hand.
Can a Lambo do any of that?
With a pen, you can perform emergency tracheotomies, too.
