The hat rack one reminded me of a flight with a Spanish airline a couple of years ago from Malaga to Madrid. CC doing pre-flight checks asked an old biddy sitting in front of me to put her bag in the overhead. After a discussion between the two she finally put the bag up only to recover it shortly after take-off. For the next 15 minutes she sat chatting apparently to herself. Intrigued, I stood to stretch my legs and peered over her shoulder to see a dog in her lap. Barking mad I call it.
