+
This comic shows a number of common events, arranged in a grid. Each of the events flashes with their average frequency.
For example, statistically a child is born somewhere on the world approximately every 0.24 seconds, or four times per second. Therefore, the tile "One birth" blinks about 4 times per second.
 
  
The title text refers to the {{w|Pitch drop experiment}} which measures the flow of a piece of pitch over many years. At room temperature, tar pitch flows at a very slow rate, taking several years to form a single drop. The title text jokes that Randall tried to include a tile that flashes about once every {{w|decade|ten years}}, but the tiles are all {{w|Animated GIF|animated GIFs}} and while the file format supports animations of any length, the resulting file would be too big (at least 10 megabytes).

Supposing that they sleep for 6-8 hours and get up to go to the toilet once per night, that means that during the rest of the day they are averaging a trip to the toilet every 3.2 to 3.6 hours. This estimate is somewhat on the high side, but members of parliament, particularly members of the Lords, do skew older, and older people tend to use the toilet more.{{Citation needed}}

|A Sagittarius named Amelia drinks a soda||7.79||7.7||4,000,000||This frequency is taken from the number of persons called {{w|Amelia_(given_name)|Amelia}} ([http://howmanyofme.com/  est. 82,572 people in the U.S.]), the number of persons born under the astrological sign of {{w|Sagittarius (astrology)|Sagittarius}} (~1/12th of the population, i.e. approximately 6881 Amelias in the U.S.) and the frequency of soda (soft drinks) being drunk (216 liters per person per year in the U.S.[http://www.nationmaster.com/graph/foo_sof_dri_con-food-soft-drink-consumption]).

This particular frequency is taken from:
