How would you react if your cousin started yelling "THE SHIP IS SINKING" on a cruise ship?

It happened two years ago, me and my cousin were playing in the cruise ship pool. And he's playing with his Titanic pool toy, which come on, he's 25, isn't he a little old for pool toys?

Then like the toy is supposed to do, it starts sinking. And he's yelling "THE SHIP IS SINKING! THE SHIP IS SINKING!"

And everyone around us is giving us dirty looks. And finally a crew member gave us a warning about "false alarms".
