Otho
From Multiversal Omnipedia
Otho was an amateur occult expert, who associated with the Deitzes. He botched a spell intended to summon the spirits of the Maitlands, instead effectively exorcizing them- Lydia Deitz had to free Beetlejuice to undo Otho's mistake. Beetlejuice disposed of the yuppie summoner by putting him in a leisure suit, whereupon he ran away in terror.
