Visible crew/equipment: In the episode where Hilary poses for Playboy, Hilary's strap-on mic is visible on the back of her red dress when she, Will, and Carlton first enter the Playboy party. It is gone in subsequent scenes.

Revealing: When Will staples his Malcom X poster to the wall, the wall bends back and forth for a second or two.

Continuity: When Phil is telling Geoffrey about his day at work he takes an aspirin and drinks the water. The glass of water is almost gone. But if you look closely a couple of shots later the glass is full of water again.

Plot hole: Ashley says she is 9; later in that season, in "Just Infatuation," Phil says she is almost 12. Will is 17 for the first two seasons, and 18 in season three. Nicky Banks grows from baby to preschooler between seasons four and five (though this was humorously addressed).

Continuity: In the scene where Will tells Vivian and Phil that Carlton is in Compton, Vivian takes off her earring from her right ear. A few shots of Will pass and when she goes to take off her other earring, the left ear doesn't have one, and the earring is on the right ear again.

Continuity: Right before Will pours the liquid into the pot, you can plainly see a fire extinguisher on the counter behind him. It's gone when the fire is actually burning.
