The tendency of seagulls to swarm if food is dropped came in handy for me once.
I was laying on the beach, minding my own business, munching on a bag of popcorn. Cheddar, as I recall. Anyway, this nasty man put his lawn chair down next to me and started blatantly hitting on me.
I told him I wasn't interested. He didn't stop. In fact, he got worse. So I packed up my stuff and moved away from him.
The guy FOLLOWED ME over to my new spot and got all belligerent and started calling me names I wouldn't even call someone who WAS those things.
So, I got up and dumped my popcorn on his head.
The sea gulls swarmed him instantly. And they're NOT scared of people in a case of a nice big banquet like that...
They had cleaned up the beach within moments, and chased Mr. Dumbnuts off to clench the deal.
God bless the seagulls.
