All of these are from Raiders of the Lost Ark really. I guess it was just so unique, it's easy to refer to it than the ones that followed it. The last one of this series is just a nod to Indy. That's something to look forward to. :-)
This isn't in the new book 300 of the Best Cow Jokes Ever! The Woc gag will of course make Vol 3 of the World of Cow comic, which will be out soon. This cow design is now a Birthday card at my Online shop. :-) There are now World of Cow Mugs, tee shirts and steins up to. Completely original and unique. Have a look at what's on offer. You can't get this material anywhere else. http://www.stikshop.co.uk/ and you can buy this toon at Cartoonstock
