This was a fun post. I would say that the first fun fact was not so fun for the guy that drowned... I guess he discovered that humans are also irrational... HAHAHAHA!
As for the number of π featured. If you include the π in the title, it would be 26. If you exclude the title, it would be 25 times.
Since we can both agree that title IS a part of any post and any text in general, I will conclude that your answer is 26. But I am not telling you if it is correct yet. See you on Saturday :)
Yeah, 26 would my attempt/guess/count. But I know I'm wrong, I've seen others answer and I think they're more accurate than I am! I forgot the pictures!
