Today host Katie Couric noticeably winced at mention of the word 'vagina' during an interview with National Ovarian Cancer Foundation spokeswoman Janette Pruce Monday. 'I understand that it's important to raise awareness and promote early detection, which is why I was happy to have [Pruce] on the show,' a flustered Couric said after the interview. 'I just didn't expect her to come right out and say the 'V' word.' An intern on the show said that Couric hadn't appeared that uncomfortable since walking in on one of the Dixie Chicks breastfeeding.
