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?
