Continuity mistake: When Willie and ALF are talking in the bedroom, the puzzle box on the bed changes position several times.
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. (00:12:55 - 00:13:35)

Continuity mistake: At the beginning, there is a side shot of Alf on the phone that has Alf saying "Sammy...shalom" with his right hand on what appears to be a phone book. When the camera cuts to the front angle, not only is Alf's right hand all of a sudden on the phone cord, but the phone book has also changed positions. (00:00:20)
Continuity mistake: When Lynn says "Mom, I need to use the phone," we see Kate raise her left hand and point then say "In a minute, dear" then when the camera cuts to another angle, Kate's right arm is all of a sudden on her neck. (00:00:55)
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. (00:10:30)
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. (00:13:55 - 00:14:30)
Continuity mistake: When the FBI agent says "We will have to call the president on that one" Brian is in the background with his hands on the edge of the stool. When the camera cuts to Brian saying "I'll call him for you" he is sitting in a different position. (00:18:15)
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. (00:04:10)
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. (00:04:55)
Visible crew/equipment: When the family walks into the kitchen after ALF was talking to Jody, you can see the set lights.

Answer: Mr Tanner actually asks Alf, "Why are you carrying our towels through the den?" The streaming subtitles are wrong when it substitutes "damp" for "den" twice. It's possible the error originated from the VHS or DVD, which occurs often.

Yes, I was re-watching episodes, and I heard "den" the next time. Thank you for answering, though.
