CLEARLY: I don't want to write down all the in-between steps.
TRIVIAL: If I have to show you how to do this, you're in the wrong class.
OBVIOUSLY: I hope you weren't sleeping when we discussed this earlier, because I refuse to repeat it.
RECALL: I shouldn't have to tell you this, but for those of you who erase your memory tapes after every quiz, here it is again.
WITHOUT LOSS OF GENERALITY: I'm not about to do all the possible cases, so I'll do one and let you figure out the rest.
SIMILARLY: At least one line of the proof of this case is the same as before.
TWO LINE PROOF: I'll leave out everything but the conclusion.
ONE MAY SHOW: One did, his name was Gauss.
IT IS WELL KNOWN: See "Mathematische Zeitschrift'', vol XXXVI, 1892.
CHECK FOR YOURSELF: This is the boring part of the proof, so you can do it on your own time.
SKETCH OF A PROOF: I couldn't verify the details, so I'll break it down into parts I couldn't prove.
HINT: The hardest of several possible ways to do a proof.
BRUTE FORCE: Four special cases, three counting arguments, two long inductions, and a partridge in a pair tree.
SOFT PROOF: One third less filling (of the page) than your regular proof, but it requires two extra years of course work just to understand the terms.
ELEGANT PROOF: Requires no previous knowledge of the subject, and is less than ten lines long.
CANONICAL FORM: 4 out of 5 mathematicians surveyed recommended this as the final form for the answer.
THE FOLLOWING ARE EQUIVALENT: If I say this it means that, and if I say that it means the other thing, and if I say the other thing...
BY A PREVIOUS THEOREM: I don't remember how it goes (come to think of it, I'm not really sure we did this at all), but if I stated it right, then the rest of this follows.
BRIEFLY: I'm running out of time, so I'll just write and talk faster.
LET'S TALK THROUGH IT: I don't want to write it on the board because I'll make a mistake.
PROCEED FORMALLY: Manipulate symbols by the rules without any hint of their true meaning.
QUANTIFY: I can't find anything wrong with your proof except that it won't work if x is 0.
FINALLY: Only ten more steps to go...
Q.E.D. : Thank God !
PROOF OMITTED: Trust me, it's true.

Create Online Mini Cities

My Mini City lets you create a new village (without registering) and then see it grow as new unique referrers are pointed towards it. The city I just created, IITB, can be seen above in its current near-empty status. But others cities like Barbelith are already much bigger, sometimes showing impressive skyscrapers.
By default, linking to your city will increase its population when people click the link. But once the city grew a bit, new links on the city sub-domain become available to grow specific sectors – say, linking to iitb.myminicity.com/ind/ will increase the city’s industry, whereas .../tra/ will push its transport facilities.
With this incentive to create backlinks, MyMiniCity.com is likely to reach high PageRank and keeps gaining traffic over time (the homepage currently has a PR5, with around 21,600 pages on the domain – many to most of them their own sub-domains – indexed in Google).
The site was created by Motion-Twin, who exist since 2001 and call themselves the “leading provider of online games for the French-speaking public.”
