Strangers in the Night - S1-E2
Continuity mistake: When Willie and ALF are talking in the bedroom, the puzzle box on the bed changes position several times.
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.
