Double Double Toil And Trouble
The original phrase is spoken in unison by the Three Witches of the Heath. They predict that Macbeth will rise to greatness, only to fall to even lower depths. The actual line is “Double, double, toil and trouble; fire burn and cauldron bubble.” The double-double aspect might conjure In-N-Out, but it actually speaks to the nature of wild exponential growth. “Double double” suggests the increasing of Macbeth’s ambitions will only lead to greater ruin, but he misses that part of the prophecy, unfortunately for him.
