Crossover with Guardians of the Galaxy. The quote at the end of this story and in its title comes from the Buffy episode The Puppet Show, which features a possessed ventriloquist's dummy called Sid:
"...How about you and I do a little rehearsing on our own, honey? You know what they say: once you go wood, nothing’s as good!”
