A blonde crashes an airplane.
Officer: Could you please explain to me what happened?
Woman: It got so cold in the plane, I turned the fan off.
Officer: *face palms self*
Also officer: Here's your sign.
Okay, so this blonde dummy thinks that the airplane's propeller, which obviously keeps the plane in the air, is just a fan to keep people cool. When she got cold, she turned off the "fan," causing the plane to crash. People like you probably think planes fly because of magic, huh?
