Three e-cards. The first is one in a long series illustrating the perils of going without punctuation — in this case, without commas that mark off syntactic constituents (in a way that receives expression in speech as well as on the page):
Then two versions of essentially the same joke, turning on spelling and apostrophes:
There is, of course, a syntactic difference in the pairs your shit / you’re shit and your nuts / you’re nuts — NP vs. Clause, to start with — a difference that is not reliably distinguished in pronounciation, since your (the possessive pronoun) and you’re (subject pronoun + auxiliary verb) are homophonous.
