Ahhhh...a long rest just can't be beat.
"Not a joke, but an incredible simulation!"
The writers put in a joke (almost always a pun), but never make or put in a punch line or explicit statement, hiding it in the set up of the joke. Some percentage of the audience will "get" the joke, but the rest will know it was there and be going, "What? Why didn't you say it?" There can be several reasons.
- It's naughty and not appropriate for this timeslot, in which case this serves the same purpose as a Last-Second Word Swap.
- It's an incredibly lame pun and is only remotely funny when realized later; using it in story would grind everything to a halt.
- Telling the punch line would keep our lawyers busy for months, so we'll just leave a blank here and let you do the copyright infringement.
- The pun is in the middle of a song, poem, or other rhythmic verse, where using it fully would break the meter.
- The pun is a form of foreshadowing, and the audience won't get the joke until later. (It's probably also a spoiler.)
- Or simply because they think they're being clever. Sometimes they even are.
The form can range a bit from a "fill in the blank" stand up style jokes to cases where the plot and setting form a pun that you only realise when you try to summarise the situation later. If you're on the Internet, expect someone to respond "
I see what you did there".
Also, as this page is about puns that are intentionally obscured in-work, it is one of the few times when it is good form to explain the joke.
