Put more curly brackets around your if (val) true statement for 4 more lines, put elses in there for more lines even.

I should have created a local variable to store the result variable and return after the if statements. I just couldn't help to make it look partially nice. My brain just doesn't think at this high caliber of LOC optimizations.

New optimized LOC version:

internal static bool AreBooleansEqual(bool orig, bool val)
{
    bool result;
    if(orig) 
    {
        if(val)
        {
            result = false;
        }
        else
        {
            result = true;
        }
    }
    else
    {
        if(val)
        {
            result = true;
        }
        else
        {
            result = false;
        }
    }
    return result;
}

My previous LOC: 12
New LOC version: 27

Surely we could optimize the return value with a switch statement and store the result as an integer to hide the compiler warning about our clearly correct code:

internal static bool AreBooleansEqual(bool orig, bool val)
{
    int result;
    if(orig) 
    {
        if(val)
        {
            result = 0;
        }
        else
        {
            result = 1;
        }
    }
    else
    {
        if(val)
        {
            result = 1;
        }
        else
        {
            result = 0;
        }
    }
    switch (result)
    {
         case(1):
             return true;
         case(0):
             return false;
         default:
             return AreBooleansEqual(orig, val);
    }
}

New LOC: 35

Make the input variables nullable, then add checks if the values are null, then assign default values if they are, otherwise continue with the passed values.

Good idea but not feasible as that could introduce unknowns. Unfortunately making defaults when null is counterproductive as we are looking to increase LOC without introducing odd behavior and having no changes to how the overall function works. The only objective is to increase LOC.
