I got a few temporarily many years ago, but they were always displaced by ScaryMike's comments.
(Back then, every day around the same time, if ScaryMike didn't have the top comment then all the top comments would get a bunch of downvotes, and ScaryMike's would rocket up several places, usually to the top. This was back when it was possible to multivote by opening multiple tabs, though I don't think it was the man himself who did it, but rather a fan desperately trying to persuade him to seek his next target elsewhere.)
The one that lasted longest was where I said the following (I don't remember what on)
CMSellers wrote:I like my women like I like my orbital death rays.
Awesome, and hopefully real ... someday.
I believe that that one lasted over two days as top comment, and wasn't abruptly replaced by a ScaryMike comment, but by someone who had posted much later than I had rising slowly through the ranks.
