Good Figures of Speech

In my post on chiches, I mentioned my liking of the phrase "bed of roses" because it came from the work "The Passionate Shepherd to his Love" by Christopher Marlowe.  Here are some other figures of speech that I like for various reasons.

"Cut the cheese"
Yes, it's juvenile and I'm willing to admit it.  The reasons I've grown to accept this one come from "The Invalid's Tale" by Mark Twain and from the episode of Two and a Half Men entitled "Putting Swim Fins on a Cat." The first tells a story about a man traveling on a train with a casket that he thought had a dead body in it (even though it didn't.  Spoiler.) because of a bag of foul-smelling cheese sitting on top of it, and the second, well, there was this song called "Who Cut the Cheese?"
(I will post the video on its own after I'm off my soapbox.  Speaking of which...)

Someone being "on their soapbox."
Reminiscent of the phrase before, I like this one for two reasons.  First of all, when I picture someone actually standing on a soapbox to talk about something, I think of a small child standing on top of a crate and screaming at her older siblings to bring her a cookie.  I have no idea why I do this, I just do.  Second, because the term "soap opera" originated from the afternoon radio melodramas that were always sponsored by different soap companies. Comparing what we know of soap operas to someone "being on their soapbox" acknowledges that people know they have a tendency to get preachy and dramatic when they are going on about something they care about, which I feel is a very important thing to be able to admit to oneself.

Some other idioms/figures of speech that I like:
-"pushing up daisies"
-"Don't have a cow"
-"snake in the grass"
-"call it a day"
-"flying by the seat of my pants"
And my personal favorite (even though I rarely have the chance to use it), "tripping the light fantastic."
