Yeah, I've had a few doozies. The ones that stick out the most are just the plain crazy people. Flying from Atlanta to Florida, we left the gate on time and then were just sitting on the tarmac. Flight attendants keep getting up and walking to a row a few behind us, which is not supposed to happen. We finally start moving again, but then my boyfriend notes we're traveling in a circle. Then we stop again. The captain finally gets on the PA and super irritatedly tells everyone that someone on the plane complained to the FAs that she thought the plane was making a "funny noise." She wouldn't listen when they said everything is fine and the plane was checked pre-flight per usual, so she called the airport, who ordered the plane grounded and sent out a maintenance crew, who obviously found nothing wrong. We finally took off and the pilot announced the FAs would remain seated the whole time and they would not be offering any food or beverage service. Pretty much everyone stared daggers at the woman for the rest of the flight. Not sure if she had some sort of weird attention issue or what, but it was obvious the pilot didn't want the FAs to have to deal with her anymore.
Another crazy lady on a New York to FL flight was just screaming and cursing at the top of her lungs complaining about the faint gas smell once we landed, claiming the airline was trying to kill us all.
