tickle (one's) fancy
To be appealing or pleasant to someone; to be intriguing or of interest to someone. A: "Do you want to go to a movie later on?" B: "I don't know, there's nothing that really tickles my fancy in theaters right now." I'm not going to declare my major until I've had a couple years in college to see what ends up tickling my fancy.

Appeal to one, be to one's liking, as in That joke tickled my fancy. This term uses fancy in the sense of "liking" or "taste." [Second half of 1700s]
