Monday morning comics: A Bizarro with word play, A Pearls Before Swine with a slogan reworked:
Another kind of hypallage (see here), with a VP adverbial (here, a little) converted to a modifier of a N: play guitar a little > play a little guitar. This particular hypallage has become conventionalized: play some / a lot of / occasional / etc. guitar.
KEEP CALM — CARRY ON is an excellent slogan phonologically: good prosody, near rhyme (note calm – on). PANIC — AND THROW A FUCKING FIT isn’t quite as compact as the model, but it has its own virtues (includling the alliteration in FUCKING FIT, plus panic - fit).
