Here are a few YouTube cartoon videos taking a humorous stab at witnessing from the Arminian or Calvinist perspective. The Calvinist one was done first and the Arminian ones were done in response. Of course, I think the Arminian ones are better and more accurate. I also found the Calvinist one a little annoying because of the canned laughter added in between each of the Calvinist responses. That seemed a little childish to me. The third one deals more specifically with the opposing views of atonement. Check them out and let me know what you think of them.
