My hot water works on a dime

This beauty was found on a facebook post:

It is a nice mashup of “works like a charm” (works very well) and “turns on a dime” (to turn very quickly or to change opinion abruptly). “On a dime” refers to agile precision, so it is close to a congruent conflation with both phrases referring to something working very well. As Tate Young says, with inflation the phrase now might be ‘works on a quarter”. A big thank you to Jenny Hensley for spotting this excellent malaphor and sending it in.
