Lard Lad confronts Homer over the stolen Doughnut.
Lard Lad was a fictional mascot turned giant-monster that appeared in the Simpsons Halloween special known as the "Treehouse of Horror" - he was originally an inanimate object but came to life after Homer Simpson literally stole his gigantic doughnut (despite the fact the doughnut was likely inedible).
Lard Lad became enraged at this blatant display of disrepect and pursued Homer - causing mass destruction in the process.
Lard Lad is very likely a parody of both Godzilla and the Stay Puft Marshmallow Man - both famous giant monsters from film.
