Stroop revisited!

OK - I hold my hands up. The last cartoon I posted was bothering me. Something was just not 'right' about it. It's taken me the whole weekend to realise what was wrong with it. I didn't know these tests were called Stroop Tasks, and I doubt if many viewers of the cartoon did either - so the joke was lost, just having two dogs in the last cartoon. I've re jigged the cartoon to make more sense.

...

Good lesson that - never be afraid of revising something to make it better. The other good lesson, is never to explain the cartoon - but I've just broken that rule!
