In an apparently unscripted fracas, Virgin mogul Richard Branson doused comic Stephen Colbert with a glass of water Tuesday when he was not permitted to discuss his new airline, Virgin America. A few minutes later Colbert retaliated with another glass of water. A member of the studio audience told the FishbowlNY blog: "Branson was apparently upset that he wasn't able to give a direct plug to the new Virgin service and doused Colbert with his guest mug of water. Stephen was drenched. ... I really don't think it was planned, since Stephen had another bit to introduce and a full interview left to do." A Virgin spokesman told the London Sun, "Richard did throw his water over Stephen. As most people know, Richard can be unpredictable." The episode of The Colbert Report is due to air on August 22.
