Doonesbury: I know I'm pretty low on the food chain, but the truth is I do enable people to order unhealthy amounts of food.

Today's Doonesbury is just a good, solid example of the character-based humor that Gary Trudeau can do in his sleep. And this kind of thing is the reason the strip is so good. The political humor is fine, and I agree with most of it, but it's the impressively textured world that Trudeau has built that really makes the comic go.

It's also a nice piece of joke construction, with a lengthy, well-written set-up leading into a short, unexpected punchline.
