eh...Tentai Senshi Sunred, or Astro Fighter Sunred is one of the newer ones that has comedic value. Each episode is only 13 minutes so it's good if you have other things to do and don't want to spend too much time anime-wise.
Lucky Star is also a popular choice, but they have a tendency of dragging on some of the scenes, although very fun to watch
Seto no Hanayome is also a pretty good choice, but the rating may be pretty borderline
Hidamari Sketch is also a really good choice comedy-wise, though it's comedy is a lot more subtle than the rest on this list
