Sitcoms and comedies

I am back with sitcoms and comedies.... first they make you laugh and laugh... and forget everything... take That's 70s Show...really. Because watching series such as CSI and such, really saddened you... because you have to think and think, plus it really saddened with all the death people... although it is interesting but really do you want to see all the crying and sad people after a long day??? Heroes... since when people can fly... wasn't it is just a big mix up of X-men and X-files? Are these important? I am thinking, NO,No AND NO!!! So, please give us more and more sitcoms please!!!
