On balance I think I prefer Nigel's version. (The rest was a typescript, I just provided a, probably unnecessary, layout sketch for the first page). Buy the Christmas Beano, on sale from all good newsagents now!
The last time I wrote a Dennis script for someone else to draw was way back in 2008 when I wrote a series of cover stories which were drawn by the great Tom Paterson during his brief stint as Beano cover artist. It was some nonsense about a mummified cat and, sadly, my name doesn't appear on it. If I ever find it in the files, I'll let you see it.
Kev F Sutherland, as well as writing and drawing Pansy Potter, Bananaman, Biffo The Bear et al in The Beano, runs Comic Art Masterclasses in schools, libraries and art centres - email for details, and follow him on Facebook and Twitter. He's been writing and drawing comics for 25 years, he must know something.
