If you read... well, any webcomics other than mine, there is a good chance that Monday's bonus Sam and Fuzzy guest strip was not the only cartoon you saw that day drawn by cartooning powerhouse Ryan Estrada.
Working diligently, and asking all us other webcartoonists not to spoil the surprise, Ryan crafted a good 30 + webcomic guest strips... which the rest of us then unleashed simultaneously. Linking to them all is a task that few are up to. Fortunately, Ryan is now gradually reposting them all on his own website.
It was a crazy undertaking, and well worth checking out. I think my
buddy arch enemy Jeph said it best:
Ryan is so awesome.
If he did this every year it really WOULD be a webcomics holiday.
