Looking sharp

I'm sure he's never heard that one before.
I tried to get the expressions right - the cheesy grin of the pun-sayer and the defeated look of the pun-receiver.
I remember eating swordfish as a kid (we had a lot of fish in our diet, which was cool since that's healthy and there's a wide variety) - I liked it. It's a lot meatier than the usual white fish like tilapia or haddock.
