It reminded me of Einstein and one of his equations in his theory of General Relativity. It pertains to Space-Time, Gravity and Black Holes and a 'mistake' he made
He knew it was there even when he published it, as it was pointed out that the answer = ∞ (infinity). And in Physics 'infinity' just won't do. Einstein replied that this 'mistake made no difference as we'll never get near a Black Hole to see the actual results.
Years later modern Physicists tried to rework Einstein's equation to 'correct it', but they made it worse.
Their answer to the 'fix' was: = ∞, = ∞, = ∞, = ∞, etc, etc, etc. 
it's pretty funny if you're into physics ;-)
