Donald Trump, The Archbishop of Canterbury and a boy scout are travelling together in a very small aeroplane.
Suddenly, the pilot comes rushing in from the cockpit in a huge panic, shouting at record speed:
"I'm so, so sorry to have to tell you this, but the engines have failed and there's no possible way to prevent this aircraft from crashing within 30 minutes. I'm afraid I have some dreadful news, though: we only have three parachutes. I feel so awful doing so, but it's my professional responsibility to get back safely and report all of the mechanical malfunctions and weaknesses in this model of plane, so that this will never happen again; so I have to take one of the parachutes. I wish you all very well; Goodbye."
The pilot puts on the parachute and jumps out to safety.
Donald Trump screams, "I am the greatest person in the world! I am a former President and almost certainly a future one as well! I am so extremely important and this world would be so much poorer without me, I'm off!"
Trump grabs one of the remaining pieces of kit, straps it to his back and jumps out, shouting "See ya, suckers!!!"
The Archbishop turns to the scout and says "Listen, son, I'm an old man and I have a very strong faith. You take the last parachute and you go back to your family and have a wonderful, long life. God bless you, child."
The boy looks in the corner of the plane and says, "That's very kind of you, Sir; but great news: we can both have a parachute and get to safety. Trump took my rucksack!"
