Good laughter or a good joke never dies.
Unfortunately, when Aunt Mildred appears on a laugh track to some crappy sitcom like 'Frasier!', her dead panties do get in a bundle.
I think it's kinda creepy to use 20+ year old laugh tracks. I mean, that assumes that people from 20 years ago find today's comedy funny . . . and that my friends, is a stretch.
Now looking back for comedy? Some things are just timeless.
