DJ and Kimmy said they did "Dirty Dancing" for their 4th grade talent show. However, they were in 5th grade when the movie came out.
On the set for the original series, the stairwell leading from the bedrooms down to the living room went to the left. The new design leads to stairs on the right, which isn't logically possible for the design of the house/set.
In the 1st season where Joey comes in from Vegas to babysit for DJ so she can have a girls night with Stephanie and Kimmy, there's the scene where Joey is upstairs with the kids and he takes their iPad's from them. When he runs towards the stairs to go down, instead of going left to go down the stairs like in the original series he turns right and goes through the the door where the attic door was in the original series to go down the stairs.
In Joey's toilet paper leaf-blower gun, it shows the toilet paper facing inwards. However, scientifically, the toilet paper should be facing outwards, in order for it to shoot properly.
Joey is seen wearing a wedding ring. We find out later in the series that he is married with kids.
Joey is seen wearing a wedding ring, but there is no mention in the series of him being married.
When Stephanie sings "Time of My Life" on stage, she mouths the line "never felt this way before", but the voice heard sings "never felt like this before" (obvious lip-synching).
When Stephanie sings "Time of My Life," she clearly lip-syncs "I've never felt this way before," but the audio of whomever is actually singing says "I've never felt like this before."
Stephanie says "So I let go, and she rams it right through her dad's bedroom wall." Should be "our dad's bedroom wall."
