Continuity mistake: In the scene where Kelso enters Jackie's room (the second time) when she is sick, she throws the teddy bear at the door. When Kelso enters there is a shot of the bear in front of him at his feet. The scene changes to only show him from the waist up (he never moves) and then changes to a longer shot where he is still seen. The bear, once at his feet, is nowhere to be seen. The shot then changes to Jackie and back to the longer shot of Kelso. The bear is now behind Kelso's feet.

Trivia: The show was originally titled "Teenage Wasteland" or "The Kids Are Alright" but those were songs by The Who and, legally, Fox couldn't get permission to use them. They renamed the show "Feelin' Alright" to show the focus groups. However, nobody really liked the name. After the focus groups airing, the audience were heard saying they really liked that show about the 70's or that 70's show - and the name stuck.
