KM3-230213A is an ultra-energetic (220PeV) neutrino event recorded by the Cubic Kilometre Neutrino Telescope (KM3NeT) on the bottom of the Mediterranean sea. The telescope consists of thousands of photomultiplier sensors suspended in the water, watching for Cherenkov radiation of the decay particles resulting from the rare collision of a neutrino with the inside of the Earth. There is no known cosmic mechanism how a neutrino so energetic could have come to be.

This meme proposes the hijinks of Apu as an alternative explanation of how all those blue-sensitive photomultipliers got activated (saturated even) in a straight line going from bottom up all at once.
