67. "Even worse than lots of exclamation points are double exclamation points!!"

"Some people use exclamation points all the time! Every single sentence is so excited it jumps for joy! Nothing looks sillier than a paragraph like this! Even worse than lots of exclamation points are--oh, no, not those!!--double exclamation points!! In formal writing, never (and I do mean never!!) use double exclamation points! In fact, don't use many exclamation points at all. Not every sentence you write is exciting enough to deserve an exclamation point, and too many make your reader tired."
