I pretty much usually ignore the laugh tracks of shows. I do realize that they can become obtrusive. I also understand that some people can't just ignore them. I just try to pay attention to the show itself, and decide where I want to laugh. Usually it's not where they place the canned laughter. I know that when I watch the DvDs I have from MASH, I turn off the laugh track. It's a shame we don't have that option on live TV.
