Two friends shake hands for 9.5 hours, set a new world record

Glad-handing was taken to new heights - or maybe it was a new low - in San Francisco Monday, when two buddies apparently set a new handshaking world record.

The American duo of Kevin Whittaker and Cory Jens gripped hands and waggled them for 9.5 hours, beating the previous record set by two Germans by a half hour.

"My elbow feels like it's about to fall off, but it was worth it," Whittaker said. "Some achievements are marked by small things. That can be a handshake, it can be a trip to the moon or a vaccine that cures a disease. We're part of that. It's epic because it's the first time this has been done in human history."
