The question naturally arises: how could many groups could have seen fluctuations in their data at the level of 3-5 $σ$ statistical significance? An example of a statistical fluctuation is given and the number of $σ$'s necessary for claims of discovery are examined. Using this guideline, a possible answer to the above question is presented.6 pages, 2 figures, Proceedings of the Hypernuclear 2006 Conference. Version 2: added one reference.
