The Comedy Unit up in Scotland, of pretty much all Scottish-based comedy the last few years fame including Rab C. Nesbitt and Still Game and more recently the excellent Burnistoun and (I'm told is excellent but haven't seen) Gary: Tank Commander and Limmy's Show, have produced Roughcuts, a podcast sketch show that is released every couple of weeks for six weeks featuring new writing and acting talent.
It's free and it's pretty funny in my opinion, 25 minutes in length so good for your mp3 player/phone for a commute. Or just to listen to in the utter waste of 40 hours a week that is your job.
<self-promotion alert> I have a vested interest as I have a sketch in episode 3 and in another episode yet to be broadcast, which is very nice for me.
It's available here for Apple-haters and probably on iTunes for those non-techies who like to appear techy.
