Gangster Ghost in Minnesota

Ghost hunters rave about these caves,
Through which flows a spammy mist,
Because in these caves are gangster graves.

Three gangsters' ghosts give tourist shock waves,
That cause their hearts and guts to twist,
When ghost hunters rave about these caves.

Miss Nina looks for mobster knaves,
Who want a hooker seeking a tryst,
Because in these caves are gangster graves.

A wraith bartender spam ice shaves,
Then pours wine with his other fist,
While ghost hunters rave about these caves.

Does Nina's corset have whalebone staves,
To keep her ghostly figure slim as her wrist,
Because in these caves are gangster graves.
.
Who among you gelled ham craves,
Are you braver then other tourist,
When ghost hunters rave about these caves,
Because in these caves are gangster graves.
