Someone who shows up to your door for no reason.
Some say he had a foot in the door... and the window... and the wall.
A low-key person
A criminal mastermind ...
The hell out of there.
Because they don't like random people knocking on their doors
A Jehovah's Witness.
They don't believe in a higher power.
All dressed up, with no place to go.
You can reason with the terrorist!
Dads joke) The same reason 10 pennies is worth more than 9.
