I remember seeing that film in the theater when I was 13. My sister and I could hardly breathe from laughing. Nowadays, it's mostly just silly, as the visual gags were not as strong as they were in Airplane. But there are still some genuinely funny moments. The ballet with the rabbit tights on backwards, with the tail on the crotch, made me fall over with laughter as the ballerina steps on them while dancing in midair.
