15 Mistakes In 'That '70s Show' Fans Didn't Notice

In the late '90s, television audiences were transported back in time to the 1970s. Only they weren't traveling in a shiny silver Delorian, but a beat-up brown Vista Cruiser!

For eight seasons, That '70s Show kept audiences laughing and entertained, but as it turns out — it managed to get a lot wrong. Have a look below and check out these 15 mistakes fans of That '70s Show didn't notice.

Talk about a Boy Blunder!

Some of those cars look awfully new, don't they?

If you look carefully at the other cars sharing the road with the Forman's Vista Cruiser, you'll begin to see that a few of them are very out of place. When Hyde is in the front seat, a 1997 Ford F-150 can be seen out the passenger window.

The WWF didn't exist in 1976.

If you look at the shirt that Kelso is wearing in Season 5's "Trampled Under Foot," you'll notice there's a picture of "Dirty Harry" with the catchphrase "Go ahead, make my day." This wasn't said by Clint Eastwood until 1983's Sudden Impact.

Oh, Canada!

If you look closely on the counter, you'll see that Kitty is using Skippy brand peanut butter. While it's true that Skippy was around in the '70s, that branding/packaging is from a current jar.

The dates of Hyde's MAD magazine don't add up.

After being interrupted by Jackie while reading a copy of MAD, Hyde tells her that he's right in the middle of reading "Smokey and the BAND-AID." However, the copy of the magazine he is reading is dated June 1976, and Smokey and the Bandit didn't come out until May 27th, 1977.

Judy Blume appreciates your support, Fez.

On more than one occasion, Fez makes mention of his love for the iconic children's book "Superfudge," written by Judy Blume. As much as it makes me happy to hear that Fez and I share the same taste in literature, "Superfudge" didn't come out until 1980.

A multiverse of madness in Season 2's "Donna And Eric Sleepover."

Eric Forman is a nerd at heart and often sleeps with a wide array of superhero sheets and bedding. However, the Spider-Man pillow beneath his head is the logo/design from the 1994 animated series — not the '70s version.

That's the wrong lightsaber.

If you look at the lightsaber Randy is playing with in Season 8's "Son and Daughter," you'll notice that it is green. Up until the release of Return of the Jedi in 1983, all lightsabers were either blue or red.

There was no choice for Sophie to make in 1978.

In Season 4's "Jackie Says Cheese," Eric jokingly says that Jackie and Kelso's breakup is "Like Sophie's Choice, but for morons." The novel "Sophie's Choice" wasn't published until 1979, and the movie wasn't released until 1982.

Wouldn't you like some pudding?

in Season 3's "Romantic Weekend," Kitty gives Fez and Hyde Snack-Packs in clear plastic containers. From 1968 up until 1984, Snack-Packs came in cardboard containers with a tin bottom and pop-off lid. After 1984, the company converted to plastic containers.
