javascript:(function(){a='jsonp';c=' .vote-count-post';d='up_vote_count';e='down_vote_count';$.ajax({url:document.location.href.replace(/(http:\/\/)(.*)(\/questions\/.*)\/.*/,'$1api.$2/1.0$3?answers=true'),dataType:a,jsonp:a,success:function(x){b=x.questions[0];$('#question'+c).html(b[d]+"-"+b[e]);$.each(b.answers,function(z,y){$('#answer-'+y.answer_id+c).html(y[d]+"-"+y[e])})}})})()

EDIT: This is longer, but it will make the result look exactly like on Stack Overflow. 521 characters, so it might not work with Internet Explorer.

Here is another one you can use on the frontpage:

It was written in Notepad already in minified form, and I used Firebug to debug. Code is above. Contribute (=decrease code size or make the output nicer) any way you want. It would be great if you'd make the second code shorter than 508 bytes.

• If a question has more than 30 answers then some of the answers won't be resolved. This can be solved easily for less than 100 answers, but for questions with more than 100 answers this is more difficult

EDIT: updated to API version 1.0.

Here is another one you can use on the front or similar pages to quickly identify controversial topics:

• If a question has more than 100 answers then some of the answers won't be resolved. For questions with more than 100 answers resolving this is more difficult (= longer script)

EDIT: updated to API version 2.1.

This small bookmarklet will allow anyone to use the "vulnerability" of the API that it allows you to check the up/down vote count - a feat you could normally achieve by being a 1k+rep user. Mainly useful for sites where you don't have this amount of rep, but want to check the stats of the more controversial questions (usually on meta)

I don't think a code like this deserves anything other than WTFPL

It's the following line (javascript - 388 bytes):

EDIT: This is longer, but it will make the result look like exactly on SO. 521 chars, so it might not works with IE.

For any jquery/bookmarklets compatible browser. Tested with Chrome, FF3.6 and IE8 for SU,SO,MSO
