This is a nice mash up of “tickled my fancy” and “it tickled my funny bone” (to make someone laugh). To laugh and be curious at the same time? Perhaps, but in this case just another great malaphor. Tickle is the culprit here, as well as the similar sounding words “fancy” and “funny”. A big thanks to “Curious Steph” who wrote this accidentally. By the way, she is starting a new blog – curioussteph.com, Check it out.
