As can be seen in this chart, "Google search results for "KH(Ax)N" for x=1 to 100," there's a real spike of "AAAAA"s around 40 and 50. That's a lot of reptitious typing! Also, you have to admire the bloody-minded perseverance of the folks over there at 97-100 "AAAAA"s. Also, RIP, Ricardo Montalban.
When I say it, it has about 50 "a"s. When JK does it, with Shatner tremors, it tops out over 100. I'm not kidding.
