What's a clue by four? Is it a reference to some timber or something of the sort? I saw one user had it next to their name after some drama.
Either way it doesn't sound good. I'm obviously missing some history here

You'd think that they'd invent some kind of search facility for users on this site, wouldn't ya ......
In fairness, the original link to the image (from a thread that started 3 years ago!) doesn't work anymore. So here's a current link: http://marcchabot.com/clue-by-four.jpg

You have me seaching for the "poster" I have hanging on the wall of my "cube" at work... I can't find it, but I found buffo's first post.

Might as well have the whole thread for context.

I will find it for you or take a picture of the one at work. clue by 4 should be self explanitory, unless y'all don't call the wooden boards used to build thing two by fours... O, that is inches so you might not. 2 inch by 4 inch board, you can hold it in your hand very well, say if it were 2 to 4 feet long (,eter or so) and could use it to smack someone in the head; giving them a clue, for what ever reason you felt the need to hit them with the two by four, or at this point it has become a clue by four.
I don't do it justice though.
