Mackerel Fish Puns

They caught the guy. When he was asked why he did it, he told the cops that it was "just for the halibut."

I'm a server at a local restaurant. A couple came in and both of them ordered fish and chips. As I'm bringing it out to them, the wife says, "Holy mackerel, that's a lot of food!" I responded with, "Actually, we use cod instead, but it's delicious nonetheless." They didn't realize what happened until I scurried away giggling.

My dad and I were fishing the river across from the church when a huge group of people came out and started getting baptised in the water just a few yards downriver. Without skipping a beat he says "maybe now we will catch a holy mackerel."
