It seems deliberately obfuscated, but just think within the function body that larry means the first thing passed in, moe the second, curly the third. It builds a list starting with the first thing, followed by a nested list that starts with the symbol moe (its quoted to prevent evaluation) followed by the third thing passed in. After that nested list comes the third thing passed in, followed by larry (again, quoted to prevent evaluation).
