xkcd.com is one of my favourite comics on the web. It strikes just the right balance of geeky witty humour without being too smart-ass.
I liked this recent one a lot :-)
A couple of other favourites:
Robin Moffatt is a Principal Developer Advocate at Confluent, and an Oracle ACE Director (Alumnus). He likes writing about himself in the third person, eating good breakfasts, and drinking good beer.
