NBC's Chuck Todd got a lesson in how to sneeze properly today when he let one fly during a briefing with health secretary Kathleen Sebelius. After Todd sneezed, Sebelius stopped the press conference to razz him about not sneezing into his sleeve, reports MediaBistro. "What's up with that? she asked. "We'll have Elmo give Chuck a special briefing," she said. Tood took it in good spirit, tweeting afterward that his sneeze is now a public service announcement.
