The agency's phone number is SurfSide6-2345.

Ken: (Offering Jill a drink) What can I fix for you?
Jill: Well, it's a little bit early for anything strong. I'll just have a martini.

Jill: I love your hair!
Daphne: Thank you. You have lovely hair, too.
Jill: Oh, I just hate it. I always wished I had blond hair so much.
Daphne: You'd be surprised how easily that can be arranged.

Daphne: Cha-Cha O'Brien's coming, too.
Don: The girl from the hotel?
Daphne: There couldn't be two of her.

Lou: Never mind the alibis, where's Jill now?
Don: I'm trying to explain it to you, Lou. We had her cornered, see, and these do-gooders jump up like a pack of Boy Scouts.

Snedigar: (Discussing message Sandy wrote on cab's windshield) Well, your agency's pulled some pretty cute tricks in the past, but this is first time I've ever heard of a stolen taxicab being used for inter-office memos.

Ken is barefoot when he lands on the ground after jumping from the top of the houseboat, but when he initially jumps from the top of the houseboat he is wearing flip-flops.

It is obvious that Ken pushes the man into the water before Sandy takes a final swing at him.

Sandy introduces Daphne to Jill as "Miss Dutton" but Jill constantly calls her "Miss Daphne" instead.

When Sandy leaves the SurfSide office he has a t-shirt on under his jacket; however, when he arrives at the Racquet Club (where he went directly from the SurfSide office), he has no shirt on under the jacket.

(Message Sandy writes on the windshield) Call SurfSide 6-2345 and tell them...

Prior to the mid-1960s, the first two numbers in U.S. phone numbers were frequently referred to by letters that corresponded to the numbers on the phone (in this case, making the phone number 786-2345). The two letters were also occasionally referred to by a word that began with those two letters. Among the most famous examples of this are the songs "Pennsylvania 6-5000," "Lonesome 7-7203," and "Beachwood 4-5789."
