A lot of the cartoons I do are based on sayings, idioms and cliche's, and this (along with 'Pear-Shaped') is a prime example. Chronologically it's one of the first cartoons I did, back in the day when I came up with one new joke a month rather than the average of five a week as now. It's not my favourite, but I was running close to my deadline and at the time I thought it was better than the other potentials. It's often the case that I'll choose a cartoon to publish based on how I'm feeling in the days beforehand. But heck, there are days when a square pig seems funny and there are days when it doesn't. C'est la vie.
