|1.||On a lighter note|
The only phrase needed when you want to interupt work-related discussion to ask about lunch plans for the day.
Scott: ...as long as we can get this done by Thursday, we'll be fine.
Todd: No problem. So, on a lighter note...
Scott: I've had jewdoba all week. I'm ready for fuckin' Hooters today.
Todd: Awesome. Let's go.
