Slimy Puns

Mediokra.

It was slimy pickings for dinner that evening.

One is a filthy, slimy, scum-sucking bottom-dweller and the other is a fish.

So a few nights ago my girlfriend said she was craving tuna. Today I'm bringing her a can as a joke, and in the car the dadjokes started rolling out:

Me: "I told her the surprise (tuna) was nothing romantic so don't get excited"

Dad: "Yeah. It's a little bit fishy"

Me: "Facepalm"

Dad: "I know, that joke was a little slimy wasn't it?"

Me: "This is going on reddit"

Dad: "Perhaps I should scale it back a bit"

Me: This is too much"

Dad: "I should just go back to the school (he's a teacher)"

Is that one is a slimy, bottom dwelling sum sucker and the other one is a fish.
