I find it weird that such an, supposedly, intelligent character as Dogbert would make basic mistakes and would say "Somalian", which is very wrong, instead of "Somali" which is the correct demonym. Just a thought...
Personally, I really like this strip. I have like 20 Dilbert books by Scott Adams from maybe 10 years ago, and some of them were just like this. I still really enjoy these types of jokes.
