Oh, the irony! What makes this strip so good is what Dilbert thinks in the third pane. If Lalalakirby stole SA's joke, she just licked off the outer coating of the humour and missed the nutrient core (i.e. Dilbert's ability to accept existence, even when his food is only what a rat left over for him).
that is really really really gross... that happend to my mom once, but it wasnt a rat, it was a dog, and it wasn't a donut, it was salted peanuts... good times...
