Fantasy Island Season 4 Episode 7

Mr. Roarke: Thank you Tattoo. There is a fluid in this vial Miss Winkler which when sipped will render you completely invisible for short periods of time.
Tattoo: Boss, is it dangerous?
Mr. Roarke: No, no, no Tattoo, not in itself, only in the consequences of Miss Winkler's own actions while she is invisible.
Harriet Winkler: I'll take that responsibility Mr. Roarke.
Mr. Roarke: Very well then.
Harriet Winkler: (taking the potion) I don't feel any different.
Mr. Roarke: But you appear different.
Harriet Winkler: Ah it worked! My clothes, this looks silly.
Mr. Roarke: Oh I'm sorry Miss Winkler, I forgot to tell you the potion does not affect clothing. Now to be completely invisible you must remove your garments.
Harriet Winkler: If you could see me now you'd be watching me blush from my head to my toenails. Aahchoo. Another thing you forgot to mention Mr. Roarke, it's drafty.
Mr. Roarke: (hands her his handkerchief) Excuse me please, I should have adjusted the air conditioner for this occasion.
Harriet Winkler: Well here goes nothing!
Tattoo: Boss, the handkerchief you gave it right to her. How did you know where she was? Oh no Boss, you can see her! Can you? Oh Boss, boss.
