Even if it isn't today, the fact that the manicule was once considered the 27th letter might be why it looks so uniquely at home in the middle of other letters, as is the case with AT☝T, H☝M, A☝W, and so on. In fact, in the business world, the manicule has uncommon status. It's the typographical equivalent of a raised finger, used to mark relationship conflicts, like Marks ☝ Spencer, Johnson ☝ Johnson, Barnes ☝ Noble, and Ben ☝ Jerry's.
…hmm, I’m not sure if this would work…
