Last week Medicare had everyone all riled up, including Sen. Robert C. Byrd.

The WaPo’s Paul Kane caught this testy exchange, which is pretty funny. The more we read it, the more we love it.

“The roll call vote was held open for an additional 25 minutes so Sens. Barack Obama (D-Ill.) and Hillary Rodham Clinton (D-N.Y.) could make it to the chamber from their fundraiser at the Mayflower Hotel. Sen. Jim Bunning (R-Ky.) grew irritated about waiting for Clinton, the last to arrive, and called for “regular order” to shut down the vote. That led to a shouting match with Sen. Robert C. Byrd (D-W.Va.), who yelled “Who are you?” and mockingly called his colleague a “great baseball man.”

“Bunning, a Hall of Fame pitcher in the 1950s and 1960s, shouted back that he has the same rights on the floor as Byrd, the longest-serving senator in history and the chamber’s leading parliamentary expert. The exchange ended with Byrd loudly laughing.”

Uh, no, Sen. Bunning, really no one has the same rights at Byrd on the floor.
