I did a thread like this several years ago and it ended up being a bit of a spammer, so I have adapted it for the year 2014. You have a 4 letter word and you have to alter one letter to make a new 4 letter word. You have to make 5 new words before you can submit a post. The goal is cover every 4 letter word in the English language. I shall begin as it is my thread and I must lead by example.

1. Cock
2. Sock
3, Sick
4. Sink
5. Pink

Please continue and if there is a repetition of a word the thread is over. If we make it to make over 200 words, then we shall likely go down as the brainiest forum on the Internet.
