A few months ago there was excited talk about the 'death of the comma' (similar to the case of the 'death of the apostrophe'). During the segment on this on Nat Rad they read out some classic examples of why the claim was so premature; I can't remember the specific examples but the internet's full of them. One of my favourites is "Let's eat Grandpa" (as opposed to "Let's eat, Grandpa")!
c.f. "Eats shoots and leaves"/"Eats, shoots and leaves" - the title of a popular punctuation book from a few years back. "Let's eat Grandpa" is a good one.
