Can I brag?
A couple of weeks ago, my GF texted me a reminder to pick up prophylactics. I sent back the single word “Roger.”
She texted back “What means ‘roger?’” (English is not her first language.)
I sent her back an explanatory link:
Subtle enough? 
Which one of the two dozen definitions applies?
Viscera.
lights = lungs and other entrails. So, “your name in lights” = using lungs and entrails to spell out a name in hieroglyphics.
A very subtle pun indeed.
Aarrggh. I totally missed it, which is embarrassing considering I was the tool who produced the line about ghee. :smack: 
Springfield’s high-end department store Costington’s stumped me for awhile. It was actually better before I figured out that it was a play on the words Costing tons, as simply having the “Cost” out there with a faux-old-money name sufficiently implied hoity-toityness. But then I woke up one day and realized it had to be a pun, and sure enough in about a minute I was :smack:
Here’s one for ya that I made up on my way to work:
How to win friends and influence people, by Dale Carnegie-Mellon.
Mellon is the Elvish word for friend
Hee hee.
It says something about the gentle art of punning that I’m happier to hear that “Aarrggh.” than the appreciative comments upthread (although those were nice and duly noted, thank you!).
Or maybe it says something about me.
It says something, anyway.
Around thanksgiving time, grocery stores put out free-standing racks of various herbs and spices for all the holiday cooking. I always found it appropriate that these were known as seasonal displays.
Bagging groceries one day, a cashier scanned a loaf of bread and then rang up a watermelon. I saved the bread from being crushed and said, “Dude! watch it. That bread was almost toast.”
In the New Testament, maybe in Matthew, a leper touches the bottom of Jesus’ gown. He says, ‘Who touched me?’ The leper was cured of course.
Cured of bleeding (hemorrhaging) by touching the bottom (hem) of the gown.
I crack myself up sometimes.
