Dunno if they're my top 5, but some of the people I like or find humorous are;
Night Fox
Wynd_Fox
Chrono
bisjac
Regulith
And then there are others, but these are off the top of my head of people I recognise and remember.
I admit that I don't know you terribly well, but your walls of text never fail to impress.
Weird, I got tons more popular since the last one of these threads.
Anyway, I don't have a top five, because some of my friends would get offended if I left them off, but my absolute favorite is Night Fox.
PS: Pennyworth, I'm not lying. :(
