Gef

George Scott's sketch of Gef the talking mongoose, from 1936
A 1932 article that suggested trickery and ventriloquism from Voirrey Irving was the cause of the Gef phenomena.

Gef (/ˈɛf/ JEF), also referred to as the Talking Mongoose or the Dalby Spook, was an allegedly talking mongoose which inhabited a farmhouse owned by the Irving family. The Irvings' farm was located at Cashen's Gap near the hamlet of Dalby on the Isle of Man. The story was given extensive coverage by the tabloid press in Britain in the early 1930s. The Irvings' claims gained the attention of parapsychologists and ghost hunters, such as Harry Price, Hereward Carrington, and Nandor Fodor. Some investigators of the era as well as contemporary critics have concluded that the phenomenon was a hoax that the Irving family perpetuated by using ventriloquism.
