Continuity mistake: In episode 10 (Joey's Place) the Tanner family move Joey into the garage, redecorating it so the entire place is filled with Joey's furniture, yet in episode 12 (Our Very First Promo), it shows the characters in and out of the garage which is completely empty and back the way it was before Joey moved in.
Continuity mistake: When Jesse, Joey and Danny start telling Stephanie and DJ the story while they are laying in DJ's bed, Stephanie has 2 barrettes in her hair. Watch closely and then there's only one barrette in her hair, and then when Danny puts her to bed, there are 2 again.
Continuity mistake: In "One Last Kiss", Jesse goes to his high school reunion and then in the flashback, he rides his motorcycle into the gym and says to his girlfriend, 'I'm graduating tomorrow, what are they gonna do, expel me?' indicating that he graduated. But in this episode, Jesse says he's a high school drop-out and he needs to take an English class.
Continuity mistake: The address of the Tanner house is 1882 Gerard Street, but in the scene where Joey brings Roxy home for a family dinner for the second time, and they are standing outside of the front door, you can see the numbers on the house are 1892 instead of 1882.
Visible crew/equipment: In the scene where Stephanie, Michelle, and Joey call the 1-800 number to report a problem with Michelle's Rigby, you can spot a microphone, for about a second, at the top of the screen right at the part where Michelle is saying, "That's us".
