It's Calamity James and Alexander Lemming! They're characters from the Beano, which is a British comic for all you foreigners out there.
They used to be my favourite characters back when I used to read it, and my drawing style now is kinda based on Tom Paterson's (the artist) style. Oooh, I do love it so!
Also, if there was a Top 10 hardest cartoon characters to draw right, i'm pretty sure Calamity James would be number 1. It took me aaages to get him looking right. Especially THAT bloody SHOE! Grrarrrhhrrhjgggh!
