I was not referencing Arrested Development. Dozens is a term that was used to describe groups of people well before AD and the context here doesn't fit the meme at all.
I am not skeptical at all that you know three people who got sick on a cruise, but out of the 30+ million people who cruise in a year it's completely meaningless. A CDC study showed that only about 0.18% of cruisers get a stomach bug
I could easily come up with a list of 24+ people who have gone on a cruise and not gotten sick. Why are my dozens less valid than your 3? You can post your anecdata but don't get mad when someone counters it with their own.
