[Graph with Y axis labeled "Mass" running from 10-30 kg to 1030 kg on a logarithmic scale and X axis labeled "Lifetime", also on a logarithmic scale, running from 10-20 to 1020 seconds.]
[There are three elliptical blobs on the graph: one on the lower left corner labeled "Mesons", another on the upper right corner labeled "Planets", and another in the middle (1kg mass, 1s lifespan) labeled "Flying water balloons". There are two bidirectional arrows pointing from the center blob to the two other blobs.]
[To the left of the chart are Cueball and Ponytail. Ponytail is throwing a water balloon, and Cueball is dodging from one. To the right are Megan and Hairy. Megan is preparing to throw a water balloon, and Hairy is slipping in a puddle of water, with a water balloon having landed near his foot with a "Sploosh!".]
[Caption below the panel:]
In the annual interdepartmental water balloon fight, meson particle physicists and planetary scientists are usually evenly matched, since they're both equally far outside their areas of expertise.
