A Public Service Announcement:

Ladies and Gentlemen,

"Thusly" is not a word. Look here. If you'll be so kind as to scroll down, you will note its origin: "thusly" originated as a way to make fun of people who were attempting to speak as if they were educated.

Articles like this (see paragraph 3, introducing the second long block quote of the article) only make the world a less-intelligent-sounding place.

In sum, don't use "thusly." At the very least, it makes you sound dumb; if that's not enough, you are also risking a serious remonstrance and perhaps some unforgiving chastising if I happen to come across it.

Stay Classy.

[As an aside, don't use long block quotes. It's called paraphrasing, for Christ's sake. Also, don't quote Anchorman anymore.]
