Are there any jokes about insurance?

A stupid guy saw a travel advertisement, and the cost was only 100 dollars, so he registered his name and paid the fee. After the travel agency knocked him unconscious with a big stick, he was thrown into the river through the back door while he was unconscious. Soon another person joined the travel agency and received the same treatment after payment. 15 minutes later, when they were drifting in the river together, the first person said, "I wonder if they bought insurance for us on this trip." "I don't know." The second man replied, "They didn't buy it last year."
