Comic book artist Patrick McDonnell is the creator of Mutts, a daily comic strip about a cat, a dog and their friends.
There's lots of references to be found in Mutts. Great fun.
Here's a couple that Beefheart and Zappa fans should recognize.
All of the above have been published in Mutts comic book collections.
