One day, a man decides to go skydiving for the first time. As he jumps out of the plane, he starts to panic and realizes he doesn't know how to open his parachute.
As he's falling to the ground at a rapid speed, he sees another man flying up towards him. The first man yells out, "Do you know how to open a parachute? I don't know what to do!"
The second man calmly replies, "No worries, mate. Just give it a good tug and it should open up for you."
The first man frantically pulls on the parachute cords, but nothing happens. He looks down and sees he's getting dangerously close to the ground.
In a last desperate attempt, he shouts out to the second man, "Hey, do you know how to land a parachute? Because mine still won't open!"
The second man chuckles and says, "Oh, I have no idea how to land a parachute. I'm just the guy who delivers pizzas!"
