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 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: 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".
Continuity mistake: In the final act, when the twins are dressed in Elvis costumes, Jessie throws the red scarves to the crowd. When he picks the twins up to bow, the scarves are back. As the winners are being announced he even removes a scarf although they were thrown to the crowd.
Continuity mistake: When Jesse and Becky are about to get married, Jesse goes sky diving because he says he hasn't done it before and is afraid he won't get the chance once he's married. In an earlier episode, a woman (from Rome?) comes to the house and tells Joey that they met when Jesse was sky diving and landed in her Alpha Romeo.
Continuity mistake: Rebecca says Danny had reseeded the grass, and it would take 3 weeks to grow, and that's why Jesse had to build the playset inside instead of the backyard. But later that very same day, when Stephanie throws Kimmy's shoes into the backyard, you can see the lawn has fully grown grass.
Continuity mistake: In the scene where D.J. and Stephanie are chasing each other, Joey and Jesse pull them apart. Then when they are head to head, D.J. has her arms around Joey's. Then, when they cut to the next shot, her arms are crossed, not even near his arms.
