One time a friend and I went to Oahu to visit another guy, and he missed when we talked about the monthly test of the tsunami warning that was scheduled that day. He was out swimming by himself when the thing went off, and he started swimming back to shore like a maniac. I never saw a guy swim so fast in my life LOL. He kept glancing over his shoulder expecting a tsunami to be bearing down on him. Right about the time the siren stopped he came stumbling and staggering out of the water, coughing and gagging, and there we were sitting on the sand laughing our asses off. Good times.
