Try this but change egg to parking space
Mark and Tom have been neighbours for several years. Mark has recently bought a hen who regularly goes to Tom's garden through a broken fence. One day, she lays an egg in Tom's garden. Mark sees Tom picking up the egg and taking it in his home. He goes outside and asks him: " Why are you taking my egg? Give it back to me!" Tom says that its his egg because the hen layed it in his garden. Soon they have a loud fight about whose egg it really is. Suddenly Mark says: " Let's solve it my way. You kick me in the balls and time how long it takes before I get up. Then I do the same with you." Tom agrees, goes back inside and puts on a pair of his hardest boots. He returns, runs to Mark, jumps and kicks his neighbour in the nuts. Mark falls unconscious on the ground. After 30 minutes he gets up again and says: "okay, now it's my turn!" Tom looks at him, laughing and replies: "forget it man, you can keep your egg!"
