Ah, Hell. Here's Jasconius.
And if you're really curious, here's a link to the Wikipedia article. Please note that my version is more of a Monty Python version of the story, and I have modified things freely, including chopping out dull chapters where I couldn't think of anything funny to do. The Wikipedia article doesn't do the story justice. I may have to fix that later.
P.S. The fact that Wikipedia uses the same pictures I do wasn't intentional---but it shows how few classic images of Brendan are available on the web.
