The Thnikkaman
From Homestar Runner Wiki
The Thnikkaman is basically Bubs wearing a pair of flashy sunglasses and a piece of paper with "TH" taped to his chest. His powers of distraction are legendary, as shown in the email "monument" where he prevents Strong Bad from completing the statue of himself, as well as Homestar Runner from finally putting on some pants. "Thnikkaman" is likely an inside joke referring to Snickers candy bars. The sale of such items by Bubs and Strong Bad's request to "have some" are evidence of this.
People also ask him for "some", although it isn't clear what "some" is. His catchphrase is "Yeah, shut up, kid."
When he arrives, magical voices sing "Here comes the Thnikkaman" and those words dance across the sky.
When he leaves, magical voices sing "There goes the Thnikkaman" also with the dancing words.
He was obliquely referenced to in virus, when Bubs' mouth as a "broken JPEG" read "TH".
