To me, Jackass is an example of current humor that strives to make us laugh at people injuring, or trying to injure, themselves or others. In, say, 20 years, when a different kind of humor is in vogue, I imagine it won't be very funny at all. In contrast, The Three Stooges are still making us laugh 60 & 70 & 80 years later. I predict Jackass won't fare as well.
