Nellie Oleson

(Alison Arngrim, right) in "Little House on the Prairie"
Distinguishing marks: Ringlets, pinafores
Weapons of choice: Insinuation, put-downs, whining
Why she's here: To prove that all little frontier girls aren't as sweet as Laura Ingalls. Playing the viper-tongued daughter of the town grocer, Arngrim was a blast of welcome bile in a field of TV corn. The name of the actress's current website? "Confessions of a Prairie Bitch."
Bully rating: Two fists
