Doit Puns

So I was making breakfast and, for some reason, my mother asked if I knew where Tuscan is. I answered Italy and she said yes and also said that we went there a good while ago. I answered "Ca doit faire mille ans par contre", wich is French for " It's been a thousand years though". Now, you must know that "Mille ans" is pronounced roughly "Mill An". She answered " Yes, we've also been there" and I groaned.
