Trying to find this short story, 99% sure it's by Stanisław Lem, maybe from the Cyberiad (I can't find my copy and haven't been able to find it online/in Google Books).
The plot is approximately ...
Three evil scientists are plotting to remake the universe in their own image. One of them is the lab assistant who gets them into the lab where the universe-altering machine is located. As his reward he wants the stars rearranged to spell his name. When the other two explain that this won't work because the configuration could only be seen from one particular perspective, he says that they can instead make the distribution of stars bunchy, because his name is "Bunch" ...
which is why the stars are bunched together (in galaxies).
