For example, are you going to laugh every time you hear something like “Dyn-O-Mite!” or “Kiss My Grits”, or are you going to start rolling your eyes after about 3 or 4 episodes of it?

If I like the character and the delivery of the line is funny every time, I won't roll my eyes. I might not laugh every single time though.

I agree with this. A catchphrase doesn't make or break as sitcom for me.

Usually I roll my eyes.
The worst of all has been bazinga.
