The World's Smartest Man (Reed Richards, universally acknowledged) and the World's Hottest Man (Johnny Storm, self-proclaimed) are home alone. Their only job is to make sure nothing untoward happens to the farmhouse while everyone else is away. But when Reed develops a magic detector that goes haywire when pointed at a specific spot in their basement - and Johnny convinces him that they should absolutely start digging up any and all cursed objects they find - things quickly spiral out of control. Will Reed and Johnny accidentally open a hellmouth underneath dear old Aunt Petunia's farmhouse? (Yes.) Will they be able to close it and fix everything before the rest of the FF return? (That's much less certain.) Ghosts and demons star in this special Halloween issue, narrated by both Johnny AND Reed!
