It's a bit of a silly, over-played comedy, with danny kaye. When ernie approves a diners club charge card for ron pulardos (telly savalas) all hell breaks loose. It turns out that pulardos is a well known mobster, busted for taxes, and wants to disappear in an arranged fire. Of his own gym. So ernie tries to get the card back before pulardos can use it! Ann guilbert (millie, on dick van dyke!) is ella, in the computer room. George kennedy is george, working for pulardos. A funny scene where ernie gets to beat up his boss at work, when he pretends to be the massage therapist. And probably the last film to feature a dumb-waiter as part of the plot! Directed by frank tashlin. Made a ton of films with jerry lewis, but died at 59 of thrombosis. Did you notice the opening song was sung by steve lawrence? Showing on free tubi channel. It's pretty good... a whole lot of slapstick and the usual misunderstandings.
