As it's been a dismal year for many, anyone got any original jokes that only make sense in the UK to lighten the mood?

I'll start. It's near the end of the Titanic film, and Jack and Rose are floating around in the water. Rose is on the door, while Jack's freezing in the water. They see a ship in the distance, and decide to make a break for it. Jack swims alongside Rose, who paddles while on her door. As they near the ship, Jack shouts out: "Ahoy! Come and rescue us!" In response, the sailors roll out a rope, but dangle it just out of reach. The captain appears, and shouts back: "We'll rescue the man for £10. To rescue the woman, we'll need £20." Angered at the apparent discrimination, Rose shouts back: "Why? The captain replies: "Because it's £10 if you call ahead, £20 on the door."
