Keep A Word/ Drop A Word Thread Fun!

Hopefully this will turn into a fun thread for everyone. How it works, post 2 words then keep a word followed with a new second word.
Example:
Post #1- spontaneous combustion
Post #2- combustion engine
Post #3- search engine
Post #4- search party

So start with search party Ready Set GO!
