A blonde drops off her dress to the dry cleaners.
“Come again!” says the woman behind the desk.
“No, it’s curry this time.”
Alright, listen up, buttercup! The dry cleaner lady tells the blonde "Come again!" which is something people say to mean "please visit our establishment again". The blonde thinks she means "what is the stain on the dress," and answers "curry". I know what you're thinking, where's the joke? Well Einstein, that's the joke.
