Maddening

Four times the fun

Does "times as many as" mean the same thing as "times more than"?
In other words, is it the same to say "200 is four times as many as 50" and "200 is four times more than 50"?
Not in my book. The first one is correct. But 250, not 200, is four times more than 50.
Use the first construction to avoid confusion.

Maddeningly common mistake

People frequently say they want to be "far from the maddening crowd." They mean instead the "madding" crowd, but because they're unfamiliar with the term, they substitute.
"Madding" means "frenzied."
"Far from the Madding Crowd" is the title of an 1874 work by the English novelist Thomas Hardy.

But what is more maddening than Madden himself?
And here's another John Madden prize: "The road to Easy Street goes through the sewer."
