Pun Intended

I saw this in the window at a local optometrist shop. [Snort!]

I love puns.  Did you know that research suggests that puns require us to use both sides of our brain in order to interpret and appreciate them?  So really, puns are brain exercise; they give our gray matter a little bit of a work out.  Some classics include

Dad jokes: "A steak pun is a rare medium well done."

Historical, a lá Benjamin Franklin: "We must all hang together or assuredly we shall hang separately."

Literary, a lá Mark Twain: "Denial ain't just a river in Egypt."

I'm thinking we need some more puns.  Do you like puns?  Have any favorites you'd like to share?
