"underpants gnomes" has been used by some commentators to characterize a conspicuous gap of logic or planning. When Sophie Rutschmann of the University of Strasbourg discovered a mutated gene that causes an adult fruit fly to die within two days after it is infected with certain bacteria, she named the gene kep1 in honor of Kenny. Political While some conservatives have condemned South Park for its vulgarity, a growing population of people who hold center-right political beliefs, including teenagers and young adults, have embraced the show for its tendency to mock liberal viewpoints and lampoon liberal celebrities and icons.

The duo has in the past reluctantly labeled themselves libertarians and fans of government gridlock. In 2006, they said that they were "rooting for Hillary
