Video clip request: Bono asks Edge "What do you think, The Edge?"

I'm well aware I'm asking for a very small clip from an infinite amount of interviews and documentaries from this band. For context, at some point my wife and I were watching something with U2 and Bono, completely sincerely, turns to the Edge and asks him "what do you think, The Edge?" To this day, I don't think I've heard my wife laugh harder. She's like "he calls him THE Edge?" It was hysterical, and she brought it up the other night and I have no idea what its from. I honestly thought it was a bit WE had made up, but she said we saw it and that's why it was so funny.

I'm not expecting anything back, but does anyone happen to know or remember what that is from? I'm trying to think of what we could have been watching. Maybe it was the Letterman special a few years ago? It could have just been some random interview. If no one remembers, that's about what I expected. But it was probably something I should have bookmarked and maybe it hasn't happened all that much in their career and someone knows what I'm talking about. As much as I love them, I really don't remember Bono referring to Edge that way. Like I've heard him call him "Edge" a ton, but not actually THE Edge, which as a fan is hilarious.
