Kim's brilliant but annoying younger twin brothers, often referred as the tweebs (twin dweebs) by Kim, both are named after their father. Their catch phrase was "Hicka-bicka-boo", followed by "Hooo-Sha". When Kim is a senior, the two go to Middleton High school because they had skipped grades. They became the Middleton Pep Puppies after Ron joined the football team and could no longer be the mascot.
