Many shows (like Mash) have anachronisms that appear to be accidental, but some of the anachronisms in that 70s are so blatant that they appear to be deliberate.

Probably the most obvious is the constant mention of "juice boxes" which weren't introduced until the 1980s.

So, can you think others? Do you think it was genuine slip or a joke?

I don't think the slip-ups were intentional -- just my opinion.

Eric's colorful bedspread had a 1990s Spider-Man logo all over it.

Other small things: The Foremans at breakfast -- A plastic cap on a Mrs. Butterworth's syrup bottle; they were steel back then. And if I remember correctly, a modern plastic French's Mustard bottle is seen; back in the '70s, the bottle was glass with a small plastic pump on top (soon to be replaced by a sort of cone-shaped plastic bottle, I think).

Watch for modern-style plastic bottles in the Foreman garage and laundry areas. 1970s detergent and auto products sometimes looked pretty different from what we're now used to.

The use of the word "hot" when describing someone who's very good-looking.
