It’s not just M-i-s-s-i-s-s-i-p-p-i.
Try M-i-crooked letter-crooked letter-i-crooked letter-crooked letter-i-humpback-humpback-i.
And if you want to take it to another level, the letter i becomes “straight letter”.
Honestly, I’ll stick to the regular alphabet.
But did you ever hear the joke “what has four eyes and goes south”? (If I wrote it as four i’s, it would give it away). It’s the Mississippi (and don’t get all smart on me and say it’s five i’s with River).
