Ectoplasm

When I first saw the ectoplasm, I was startled at first, Then I remembered, I drive an old hearse Maybe there's a way, to make this thing pay, So what do you say? Give advise, if you may... So I conceived of a plan, Daring for any man... I got a fire extinguisher Whose foam was like cold ice, When he next appeared, I used this device... I packed him in a cooler, filled with dry ice... Brought him home, and into the freezer, Space was quite tight, I really hadd'a squeeze her... Now anytime I need a ghost, Like unwanted guests, for an unhappy host, I'll let my spirit thaw and rise to the occasion, In hopes their fright will be as strong, As it'd take to change a black, to one scared caucasian.
