Roger Ebert on the f-word in Hot Tub Time Machine
From his review [re]:
I can't be sure, but I think the density of the f-word reaches the saturation point in "Hot Tub Time Machine." I may have heard it employed as three different parts of speech in the same sentence. One wonders if American-spoken English could survive without it. What did we say in the old days? It must have been a quiet land.
