I think that's the name of the movie. Anyway, Cary Grant touches Katherine Hepburn's sides to move her out of the way, and she jumps, and he says "Oh I see you're ticklish." Not a great scene, but ok. I wonder if he's tickled anyone else in movies?
That's amazing, that would make 3 scenes Cary Grant as tickler! Ginger Rogers in some movie when he's pretending to be fitting her for a dress, and a great one in The Awful Truth (I think it's called) where he keeps poking a girl with a pencil on the side. Both scenes you can see he's tickling her convincingly and the laughs are great.
