**The Maximally Satirical Sandbox Model (MSSM)**

The Maximally Satirical Sandbox Model is a model of an ideal sandbox, which can be stated as follows:- continued collaborative perturbations to the "Sandbox functional" results in \(\delta S=0\) where *S* is satire. This is equivalent through a simple *R* transformation (where *R* is reflection), to the Minimally Satirical Sandbox Model. The knowledge of the existence of knowledge of these two models can then be used to prove the PhysicsOverflow concavity theorem.

**On the non-perturbative formulation of sock theory and the long standing missing sock problem**

The Minimally Supersymmetric Sock Model (MSSM) is a supersymmetric \(\mathcal{N}=1\) matrix model that describes socks and sockinos. Socks are described as spin-2 massless particles while sockinos are described as spin 3/2 particles. Spontaneous supersymmetry breaking causes sockinos to gain mass, which explains the spontaneous disappearance of socks and their decoupling from the sockinos, besides when in a high-energy state, during which both sock disappear spontaneously and couple with their respective shoes and shoeinos (they are prevented from decoupling from their shoe because of Sock exclusion).

The Minimally Supersymmetric Sock Model exhibits S-duality with the Minimally Supersymmetric Shoe Model (MSSM). This means that a strongly-coupled sock is equivalent to a weakly-coupled shoe. This is unsurprising, because a very tight sock is the same as a very loose shoe, but the reverse is much more astonishing: a weakly-coupled sock is equivalent to a strongly-coupled shoe, i.e. a very loose sock is the same as a very tight shoe.

The Minimally Supersymmetric Sock Model also exhibits T-duality with the Minimally Supersymmetric Glove Model. This means that a very small sock is a very large glove, and vice versa.

This is an answer to the unsolved problem posted on Stack Exchange a few years ago, that was unfairly closed as being off-topic, despite the strong correlation observed by Shoesock Gloveson between the percentage of off-topic questions and the overall quality of a site.
