Help me think of a joke to make my girlfriend happy, please!

Humorous joke: Two people have been in love for three years. They made an appointment to practice horseback riding in the mountains. The man rode the horse to the edge of the cliff. He turned back to the woman he loved and said: "Let me ask you one last question, can you do it?" Marry me, if you don’t marry me, I will jump off this cliff.” The woman was moved and shouted “Marry!” to the man, and the horse rushed down the cliff with a cry... The man was 28 years old. .
