Working My Way Back to You - S2-E1
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: When Kate tells ALF that he's won she is not holding anything. The shot changes and she is now holding an orange.
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.
