If you happen to read the back section of the in-flight magazine, you'll notice that the airline advises you to stretch throughout the flight to keep the blood flowing. Usually, that means doing a few knee lifts while still buckled up in your seat, but it seems Uma Thurman recently took this advice a a little too literally.

The actress reportedly stunned fellow passengers when she started doing yoga in the aisle of a flight bound for Salt Lake City. Says one passenger, "Uma started doing yoga in the aisles. She used the flight-attendant station as a ballet barre, where she stretched and did plies for 20 minutes." The most ironic part of the this story? "After we left the plane, she ran for an exit and then chain-smoked like crazy." Ick.

Chain smoking aside, what do you think of yoga at 30,000 feet in the air? Bizarre or perfectly normal?
