In the simplest case, the thing referred to is 'a think', and they're entirely equivalent :) I'd argue that this is more of an Eggcorn[1] than a malapropism, unlike your second example. "The proof is in the pudding", or the classic "Could care less"[2] are the two worst offenders I can think of immediately.
