While the Huns did in fact, exist, Atilla, leader of the Huns was not called Attila the Hun at all, but Attila the Cunt.
Joe Hun: What an absolute fucking cunt.
Larry Hun: I don’t think I’m exaggerating when I say, he was a real cunt.
Jeb Hun: We had many names for him. Atilla the Hunk, Attila the Punk, Attila the Spunk, Attila the Skunk, Attila the Drunk, even Attila the Munk. He’s the one who came up with Attila the Hun – thinking himself some kind of leader. That narcissistic cunt.
