Welcome to the home of the Fun Unit.
A fun unit is the unit for measuring fun. We have found scale of fun to be defined by two points, a Fun-Size Snickers(tm) being equal to one (1) fun unit. And a fun noodle is equal to ten (10) fun units.
We theorize that the range of fun is 0 to 100, as the most fun things have been determined to have fun units approaching 100. To this date nothing with a perfect 100 fun units has been found. 0 means no fun, whatsoever. The number of fun units that something has are a quantification of the magnitude of entertainment it provides, and the duration of such entertainment.
