If anyone does have HBO, Flight of the Conchords is an excellent choice. It's a silly comedy about two guys from New Zealand trying to "make it" as a quasi-folk band in modern New York despite the fact that their manager is completely incompetent and they only have one fan. It's genuinely funny, not overdone, and the extremely likeable main characters break into hilarious and clever songs throughout the episode. Not to mention a fabulous supporting cast. I think they're starting the 2nd season soon.
