Senate Majority Leader Harry Reid reopened the Senate today after a five-week recess, wasting no time before launching a broadside against Rep. Paul Ryan, the GOP vice presidential nominee.

Reid, four sentences into his speech, poked fun at Ryan's earlier misstatement of the finishing time he ran in a marathon two decades ago.

"I ran the Boston marathon. And using the Ryan math, my time would not have been a world's record, but within minutes - minutes - of a world record," Reid said from the Senate floor. "I could have made the Olympic team. Using Ryan math, I would have been superb."

Paul Ryan had claimed that when he was younger he had once ran a "2 hour and 50-something" marathon, a remarkably fast time, prompting some to dig up that Ryan had actually finished the marathon in 4 hours, 1 minute and 25 seconds.

Ryan has since explained the statement, chalking it up to it being a long time ago and hard to remember.

"I literally thought that was my time. It was 22 years ago. You forget sorta these things," Ryan has said.

Reid used the mistake to try to make a connection to Ryan's calculations on other more consequential things like the congressman's budget plan.

"His math doesn't work for running a marathon or anything else. The Ryan math doesn't work with his budgets, it doesn't work with Medicare. It doesn't work with his tax plan," Reid said today.

This is the first day Congress has been in session since Rep. Ryan, the chairman of the House budget committee, was chosen as Republican presidential candidate Mitt Romney's running mate.
