In America we offer the skeptics challenge: “Yeah, right?’’
In the UK it’s: “Too right mate!’’
That's funny. I've never heard that and I watch a lot of British made TV shows. Another one that I've always found strange is that they use the line "Did you have any joy"? That's in relation to having any success with doing something, like in a detective series, having any luck finding a new connection or new evidence.
