Imagine being stuck on a six hour flight with a woman who refuses to stop singing Whitney Houston's "I Will Always Love You"...badly.
It got to be too much for either passengers or crew to take, so the pilot diverted and made an emergency landing in Kansas City. This clip is from when the woman was escorted off the plane, still singing. Amazingly, she was later released without being charged. I would have thought they might have been able to make a charge of being disorderly, but I guess they either couldn't, or felt sorry for her.
