Rewrite 1: I must be in an echo chamber, I'm saying it again!
Rewrite 2: I could swear I've heard me say this before
Rewrite 3: Let me say it for the thousand-and-first time...
Rewrite 4: maybe you didn't hear it the first thousand times
Rewrite 5: I've said this hundreds of times already, but let me repeat one last time for effect
Comment: There's a lot of sarcasm present in these rewrites, perhaps because the original is so close to stating the case with only some exaggeration. Can you say this in a meaningful way without sarcasm?
