So why is this fun? Or did you mean it is fun to watch from a safe distance?
It’s especially fun to catch squid on a hot day, on a hot day, when they shoot streams of water at you.
To catch squid, you need a squid jig, a plug studded with sharp spines—they will slip off a regular fish hook. Squid aren’t very smart, so when you throw out your jig into a school of squid, one will almost always grab it. Soon, you’ll have a bagful.
