-Megan and Cueball have detected a person using their device, by the fact that it generated two yells during the scan, possibly from impacting the person's face and another sensitive part of their body. They intend to repeat the experiment to determine the person's height, by working out the angle of the tennis balls that generate the yells. Combined with the velocity and time to impact, this should give them enough information to work out the height above ground at impact and the distance from the launcher. The joke is that this height measurement could probably have been completed with a visual assessment, and with far more accuracy than using tennis balls to approximate their height. Most humans work with large-scale objects in their day-to-day lives and hence do not see by using a microscope, although the lens in the eye operates on the same principal as the objective lens in an optical one. This method is also likely to be problematic, as the person would likely duck or run away in response to being bombarded with tennis balls, affecting future measurements. This is known as the {{w|Observer effect (physics)|Observer Effect}} as well as a normal {{w|Sampling (signal processing)#Practical considerations|consideration of sampling}}. (It may also be why the 'scanning' is done from the top down, as early {{tvtropes|GroinAttack|low-hitting projectiles}} might reduce the height that later projectiles can detect.)

It would not be reasonable to produce this effect at tennis ball scale with any typical building wall, but naively attempting to do so by launching tennis balls at a sufficiently high velocity (the required speed dependant upon whether they are aimed at the likes of plasterboard, brick or concrete) could lead to damaging the wall instead. "Scanning Tunneling Tennis Ball Microscope" capable of launching tennis balls at velocities, sufficient to do large holes in lab walls (presumably, concrete), could be very useful as a weapon—especially if tennis balls were swapped for stronger projectiles (e.g. tennis-ball-sized lead or steel bullets).
