What Ghost Can You Catch If You Don't Have Money?

On the podium, a host in a suit and ties was describing the latest ghost-catching regulations: "Taxes will be collected if you catch ghosts, tax will be charged if you let go of ghosts, taxes will be collected if you see ghosts, and taxes will be collected if you are scratched by ghosts. Taxes will be collected if you use magic weapons, and taxes will be collected if you don't use magic weapons..." "What nonsense are you talking about?" Some discordant voices sounded from the audience. "You have to collect taxes even for this nonsense!"
