Denny’s is a so-so restaurant that is certainly haunted by the ghost Denny himself. Eating at Denny’s can result in impulsive eating and blacking out, this is a result of you becoming momentarily possessed by the hungry spirit of Denny.
Person one: “let’s eat at Denny’s tonight”
Person two: “no. Not since Denny possessed me last weekend”

Get the dennismug. A 24 hour diner, that gives jobs to slutty girls. And hires retards to manage the place. You'll always find a creppy guy working night shift, or a lady missing some teeth and talks to her self. but the do have an amazing hot fudge brownie...
