Once during a approx. 10 hour flight, a heavy, older woman was seated next to me. Shortly after she claimed my her armrest completely for her own, for the whole flight, she just started telling me her whole life. With no chance to escape, I pretended to be interested in listening, hoping she would be finished soon ...
She told me to be a ballet teacher. To that date I ever believed ballet dancers would be young and attractive. Apparently, unfortunately once again I had bad luck with my seat neighbour.

Soon the service started. She ordered her first beer. She told me she likes beer very much and needs it to be able to sleep later on. Great idea, I thought, she won't be able to talk while sleeping what brings me hopefully a few hours of peace. But unrested she continued till the next service. She ordered one beer after another. From beer to beer the became more communicative. After many hours she started babbling nonsense and finally fell asleep.
Now I would have had some peace, I thought. But no! Soon that "monster" started snoring like a freight train! And won't stop!
Of course, exactly on time to breakfast she woke up and guess what she ordered for drinking? Right, a beer! I didn't even know they serve beer for breakfast! But to my amazement the flight attendant just did without further asking.
Time went by and only one hour left till landing. Good idea to start filling out the immigration form now. She did like I did. But another, still pretty full, cup of beer still remaining on her table (I stopped counting) was in the way. She finally knocked it over herself. She was completely wet of beer and her imigration form swum away. Immediately the brewery smell filled the cabin. Thank god it happened just a few minutes before landing!

The last time I saw her was lurching, still dripping wet, at baggage claim.
