Corrected entry: In the new season (2003-2004) there's a show where Kelso drinks raw eggs to amaze Jackie, he swells up because he is allergic to eggs. However you see him eat brownies and peach cobbler in previous seasons and those desserts include eggs in their ingredients.
Corrected entry: Red gets mad when Eric says Nixon was a crook, but in the episode "Streaking", Red asks President Ford why he pardoned Nixon.
Correction: I don't think that Red gets mad because of Nixon. The real reason he gets mad is because Eric uses it to make a joke about Republicans.
Babe I'm Gonna Leave You - S5-E14
Corrected entry: They bring up Starburst, but Starburst never came around until the 80's.
Correction: According to the Starburst website, the candy was "invented" in 1960 and first introduced in the U.S. in 1976. So the gangs references to Starburst are completely legit.
What Is and What Should Never Be (1) - S5-E3
Corrected entry: Red complains to Kitty that the Corvette will be the first thing to go when the new baby arrives, and that he had been wanting it for 25 years, but couldn't afford it with the kids. However, the Corvette is a '58, which would make it 20 years old, and even Laurie would have been born long after the Corvette was originally introduced.
Correction: Just because he had seen it before the kids were born doesn't mean he was in a position to buy it. After they were stable he would have been able to, but now couldn't because of the kids.
Correction: Yes, but it is raw eggs that he is allergic to. I'm allergic to food colouring in raw cake, but not when it has been cooked. Brownies and peach cobbler have been cooked.
