Continuity mistake: At the beginning of the episode, Mrs. Tanner scolds her son Brian for dumping all of the clothes from the clothes basket. When she first scolds him the basket is white; it cuts again to her, and now the basket is brown and a different shape, too.
Continuity mistake: After Brian finds the note Alf left, we see William put the note under the microscope to inspect the tear drops. When William says "I'm going to go find him," he stands up and we see him leave the note on the microscope. When the camera cuts to William walking through the door, he all of a sudden has the note in his hand that was left on the microscope.

Continuity mistake: After Trevor shows Kate and Willie the house for sale sign, Alf is in the kitchen talking into a tape recorder about being blackmailed. There are soda cans to Alf's right next to the recorder and one can of root beer on its side just above the recorder. When it cuts to Kate and Willie walking into the kitchen, the downed can has been moved, and the red can of cola is gone. After Kate says "And it wasn't my mother, either", there's a close up of Alf and the cans are back.

Continuity mistake: After Raquel leaves the Tanners' house after she asks the Tanners about Elvis being next door, Willie walks into the dining room and Alf is sitting at the table with the Elvis sightings book next to him. Throughout the whole "Kings comparison" between Willie and Alf, the book on the table changes positions after every few cuts from Alf to Willie.

Continuity mistake: After Willie takes Alf into the kitchen to talk to him about someone at the Halloween party might realise that he's an alien, notice the zipper on the front of Alf. Out of nowhere, during one cut, a piece of black tape appears at the top of the zipper going across the top of Alf's chest that wasn't there before, then disappears in the next cut.

Continuity mistake: When Alf calls Air Force One the second time (after Willie has been arrested) we can see that Mr. De Foe is playing solitaire. After the guy who answers Alf's call says "You might want to try that 4 of Spades on that 5 of Diamonds", Mr De Foe drops a small stack of cards on some of his already played cards and says "Just place the call and trace this one." The camera then cuts to the guy who answered Alf's call but when it cuts back to De Foe, the cards he dropped are now neatly stacked in front of him with out anytime to have replaced them. After the cuts of De Foe talking to Alf, De Foe eventually saying "I'll see what I can do" and the cards are back lying on his other cards like they were when he first dropped them.

Continuity mistake: After Dorothy tells Alf that her 'mop from the moon" comment was an insult, Alf says "If I had a straw and a napkin, I would fill you so full of spit balls." while Dorothy is looking right at Alf but when the camera cuts to just Dorothy, she is all of a sudden looking upwards as she says "Do you hear how he's talking to me?"
Continuity mistake: After Willie and Alf talk about what's for breakfast, in the far away shot Lynn has a bottle of orange juice and she begins pouring it into a glass, then she starts putting the lid back on the bottle. When the camera cuts to a close up of just Alf and Dorothy, not only is the bottle of orange juice already sat down but Lynn starts to grab her glass of orange juice without anytime to have put the bottle down, let alone to start to pick up her glass.
Audio problem: After Alf calls the radio station and tells the station to give Jody his phone number, Alf walks to the towards the table saying "Friend...wish I had one" with the phone in his hand. Right after Alf says "Friend..." listen closely in the background and you can hear a far off phone ringing about 2 seconds before the one Alf is using starts.
Character mistake: During the radio show, the radio host gives the radio station's phone number as 555-4455, Alf then softly repeats the number back before he gets to the phone. He then picks up the headset and dials a number, but the numbers he presses on the phone don't match up to the number given by the radio station.
Continuity mistake: After Willie is arrested, he is talking to Kate while he is in the jail cell. Willie then begins to say "I don't know what happened. All I know is someone used my radio and now I'm a criminal and they're going to hang me" with the camera view being behind Kate with Willie's hands outside the jail cell bars. Then when the camera cuts to inside the cell, Willie's hands are not only inside the cell but Willie is further back away from the bars with his hands inside the cell, with no time to have made the move.
