As we all learned a long time ago, there are 26 letters in the alphabet. But there might not have been. Here at Mental Floss, they examined a dozen letters that might have made the list but didn't for one reason or another.
It's kind of interesting that the ampersand might have made it as an actual letter, instead of a symbol. Of course, as I remember from reading Beetle Bailey, sometimes the ampersand serves as a letter, appearing in place of the curse words that Sarge speaks as he is stomping Beetle into the ground. But I bet at night, when all the real letters are asleep, the ampersand dreams of an alternate universe in which it takes its rightful place in the pantheon of the 27 letters of the English alphabet.
Keep dreamin' li'l curlicue. You never know what might happen someday.
