Host senseless spam games.  This one is simple and fun:

Step 1: grab a book
Step 2: copypasta the opening line
Step 3: add "and then the murders began"
Step 4: ???
Step 5: profit

For example:
"Here you are, Menolly," said the dragonrider, "Safe and sound in the Harper Hall." And then the murders began.
