I used to do the same thing. Then I decided to actually look up the saying and found out they are both pretty coming British phrases. I was very disappointed.

it's like giving them an all tomato.

I've never seen "Community" and I've never lived in Great Britain but even I know what "streets ahead" means.

That's usually when I use my escape goat.

They may be a community watcher, or they may be British. Further investigation required.
