It's Friday! Friday! And while we know you've gotta get down on Friday, why not do it after you've enjoyed this week's round-up of funny tweets?

Yes - we've tried to put the sad demise of Ceefax (and two racehorses) behind us, and have instead concentrated on wrangling the lovely jokes, puns and silly one-liners that have emanated from Twitter this week. As always, it's been a big job, but someone's got to do it. Especially now that intern has left. Enjoy!
