An {{w|Astronomical interferometer|astronomical interferometer}} is an array of separate telescopes that are able to work together as a single telescope, effectively providing higher resolution using a process known as {{w|Aperture Synthesis|aperture synthesis}}.

In the comic, [[Beret Guy]] and [[Cueball]] are walking Beret Guy's dogs when BG makes a comment on how interferometry is really cool. Interferometry is the practice of overlapping two different waves to get a different signal, which can be used to determine the distance between two reflecting surfaces. Beret Guy states that two dogs placed at a consistent interval will function as a larger dog. While this idea works on waves, it probably won't work on dogs{{Citation needed}}, which is why Cueball is confused and starts to correct him. Before he can respond, however, Beret Guy jumps on this "large" dog and appears to be floating in midair. The large dog is further proved when it gives out a large bark. Cueball looks on speechless while Beret Guy appears to exhibit another of his [[:Category:Strange powers of Beret Guy|strange powers]].

The title text states that the effective giant dog is not any more 'good' than the two original dogs. This is analagous to sensitivity for astronomical interferometers. Interferometery does not increase the light-gathering area, so it cannot view dim objects as well as a single large telescope could. It could also be a reference to dog-owners often refer to their dogs as "good dog" or "good boy/girl", and will ask the rhetorical question "who's a good dog/boy/girl?", or just that a giant "bad" dog might attack the owner.

:[Cueball is walking with Beret who is walking two small dogs.]
:Beret Guy: Interferometry. Is so cool!

:[Beret Guy placed the dogs a small distance apart.]
:Beret Guy: If you put two small dogs a large distance apart, they can function as a single giant dog.

:Cueball: I'm not sure that's-
:[He is cut off by Beret Guy jumping onto the "giant dog" which still appears to be two small dogs.]
:Beret Guy: HYAH!

:Giant Dog: '''WOOF'''
:Beret Guy: Away!
:[He rides away on the "giant dog" which still appears as two small dogs, the "giant dog" gives out a large bark.]
