Aye, I think Fat Boab was a pal of Oor Wullie. P.C. Murdoch perhaps not quite so much!
And was there also a pal called "Wee Eck" or something similar?
If I think any more about this, I'll soon be getting the Oor Wullie universe mixed up with the Bash Street Kids and Desperate Dan with his cow pie and Lord Snooty and Beryl the Peril and who knows where it will all end? And the Four Marys, whichever comic that was in.
