100321- A joke

.....Since I've started this daily joke blog, I've noticed how difficult it is to use classic pun-based riddles in this medium. For example, if you're speaking to someone face-to-face you can ask, "What's black and white and read all over?" The answer is "a newspaper", but because "read" is a homonym for "red", and you list it right after two other colors, you've misdirected the person trying to answer the riddle. The essence of punning, right? The problem is, printed words aren't conducive to homonyms; you're limited to only those words that not only sound the same but are spelled the same and have different meanings.
.....Of course, the bigger problem with that particular joke is that the punchline is no longer true: newspapers are no longer read all over anymore. When they were, the joke had circulated so prevalently that a second level of misdirection became possible: you could ask the same question, and persons prepared to reply "newspaper" would instead be given a punchline based on the word "read" actually being "red". What's to become of all those jokes when the cliche they are based on dies out? I propose we give them a formal retirement. This week I'll do one per day.
