So a teacher, a politician and a psychologist were on a plane.....

(the types of people in this joke doesnt matter)

So a teacher, a politician and a psychologist were on a plane. They were all a bit drunk so they started throwing things off the plane.

The teacher threw an apple out of the plane
The politician threw an orange off the plane
The psychologist threw a grenade off the plane

When they land they meet a girl who was crying so the teacher goes, "why are you crying?". Then the girl says, "an apple fell on my friends head then he died"

They meet another sad girl. The politician says, "why are you sad?" To which the girl replies with "my mum was killed with a flying orange"

After that they meet a man that was happy as, can be. The psychologist asks, "why are you so happy?" then the man says,
"after I farted the building behind me exploded!"
