The Unshelved cartoon from the 12th, passed on by Betsy Herrington on Facebook:
The GN takes a truly extreme (One Right Way) position that like can be only a verb, a bizarre view that results in her seeing the library poster as being incorrectly punctuated. (Ok, when in doubt, blame it on the punctuation.) She doesn’t even recognize the preposition use (Which one of these things is not like the others?), not to mention the many uses of like that are set off intonationally in speech and consequently should be punctuated with a comma — no doubt she dismisses these as simply incorrect, “not English” — in particular, quotative like (I asked when she was going, and she was like, “In a minute”) and discourse particle, or discourse marker, like, as in the library’s poster.
