That shirt doesn't really work for me. The saying I've always heard was, "If I've told you once, I've told you a thousand times". So the N/N+1 thing doesn't really fit.
But maybe the saying is different for other people? I've never heard anyone say "If I've told you once, I've told you twice", or "If I've told you 5 times, I've told you 6 times"...

Eh...it's probably just me. :)
