During today's swearing in ceremony at the Senate, Vice President Joe Biden tells a freshman senator's daughter "no dates till you're 30." The unsolicited advice receives resounding laughter, giving Biden the idea that he should say it again to every girl under the age of 30 he meets that day. ABC News compiled the introductions in an awkwardly repetitive video that reminds The Washington Post's Rachel Weiner thatBiden has definitely made this joke before--for example back in October. "Of course, Biden and his wife Jill met on a blind date when she was merely 23," notes Weiner. "If the vice president has dating advice for young men, we have yet to find video of it."
