This comic shows a life sized ship in a bottle sailing along with other sail boats in the sea. The humor comes from the surreality of the situation.

In this comic, [[Beret Guy]] is inside a {{w|Impossible bottle#Ship in a bottle|ship in a bottle}}. [[Cueball]] and [[Megan]] are in a sail boat to his left, while [[Ponytail]] is alone in a sail boat to his right. A common question the other three sailors might have is how Beret Guy’s ship was put inside the bottle, due to the small size of the opening in the bottle compared to the ship. The answer is that the ship was assembled (or at least partially unfolded, from more compact original components assembled outside) within the bottle. The components are small enough to pass through the neck of the bottle, and the final assembly is likewise done by growing the enbottled form into its fully expanded size (everything necessary having already fit through the neck), usually the most awkward task. Of course, toy boat assembly is not comparable to real or life-sized ship construction, especially considering that toy boats usually do not float{{Citation needed}}.

The title text alludes to this, by saying that Beret Guy, when he was smaller, sailed the boat inside the bottle while he was still able to fit through the entrance. This is similar to the way some brands of pear brandy are sold in {{w|Impossible bottle#Small objects that expand naturally|bottles containing entire pears}}. These are produced by attaching the bottle to a young fruit and letting it grow to full size inside. This explanation fails to address that Beret Guy would fit through the neck of such a bottle relatively easy, on his own; but the boat, being made from non-living materials, would '''not''' have grown inside the bottle, and it is unlikely to have ever been a smaller boat carrying a smaller Beret Guy, and in a manner that both together could have sailed into the bottle. On the other hand, it would probably be easier for someone inside the bottle to have assembled components of a ship there than for that assembly to be directed from outside. This would especially be true of a seaworthy vessel of a size to carry a passenger, rather than a mere model. But it’s possible that he used one of his many [[:Category:Strange powers of Beret Guy|strange powers…]] Also, given the definition of boat explained in the earlier comic [[2043: Boathouses and Houseboats]] ("a ship, by most definitions, carries boats"), Beret Guy's vessel is merely a boat.

The water level in the free-floating bottle is lower than the water outside. This is because the bottle will sink until the weight of the bottle and its contents (the water, the boat, and [[Beret Guy]]) equals the weight of the water displaced by the bottle. The weight of the 'missing' water in the bottle (the layer of air between the two surface levels, including the corresponding volume of air displaced by the boat) is consequently equal to the weight of the whole glass bottle. If you added water to the bottle in an attempt to make the inside and outside water levels the same, the bottle would contain less buoyant air and just sink deeper to misalign the surfaces again. Keep repeating this, and the boyancy becomes less than zero (unless the inherent buoyancy of Beret Guy and his boat, now forced into the bottle's 'ceiling', still possess enough intrinsic support) at which point the bottle would sink.

In practice, the bottle is horizontally unstable. The weight of the bottle is not equal along its length (it appears heavier at the neck), and the boyancy at each point will not equal the weight at that point. This is also true of the boats in the cartoon, the difference is that in the bottle much of the weight is the water which is free to move. If the neck of the bottle goes down (to increase the displacement to balance the weight), the water will move to the front of the bottle. This increases the weight at the front which will force the front even deeper. This will continue until the bottle is floating vertically. [[Beret Guy]]'s boat would appear to fit in the width of the bottle so everything will be fine. This effect (known as the 'free surface effect') has real implications for ships with open decks, such as car ferries, and has been implicated in several disasters such as the 'Herald of Free Enterprise', the 'Princess Victoria', and the 'Estonia'. So the bottle is ridiculously impractical and the only thing it would do would be {{What If|103|protecting}} the people riding the ship.

<!-- What kinds of boats are we looking at? How large would those be in real life, and would they be seen on the open seas? -->

[Three small single-masted sailboats are shown, all sailing towards the right. The ones on the left and right are on the ocean, while the one in the middle is contained completely by a large bottle. On the left, Cueball and Megan are in one boat; Cueball is near the stern, possibly holding the tiller, while Megan is before the mast. In the middle, Beret Guy is before the mast in the boat that's inside the giant bottle, with a cork plugging the bottleneck. On the right, Ponytail is directly aft of the mast of the third boat. All the boats are sitting on the water with ripples on the surface, but the water level in the bottle is lower than the rest.]
