Theoretically speaking, shouldn't two "U"s, when placed side by side, make the sound of a W because there are double the amount of "U"s? hmmm...
Theoretically yes, but first of all, are there any words like that? Because I can't think of any. And if there are, I'm going to do that from now on.
Oh my god! I am officially declaring that from this day forth the English language word, "Vacuum", shall be pronounced Vacwoom.
