Y and Z are for

Y is for Yule Log

I know not why it came into being--actually I have a vague inkling and with some research I could find out for you--and today I don't really care. All I'm going to do is cut myself a huge slice of that chocolatey goodness and sit back and relax.

Z is for zzzzzzzzz
Because I'm just knackered. 
Next time I think it's a good idea to do 25 continuous post remind me how time consuming it is and how little writing I actually get to do!
