On Jeopardy, there are clues called "Before and After" which asks contestants to answer questions like

```
Period of rest in Genesis where working parents leave toddlers
SEVENTH DAY CARE CENTERS

```

However, I'm sure this form of wordplay has a name and existed before Jeopardy. I once stumbled across a list of examples of people chaining together 30+ words in this way, but I can't for the life of me find it. Does anybody have any references to what these are called, or where I can find impressively long chains?
