 The next day , Lisa calls home to tell Marge of the news ; Marge promises that she will prevent Homer from ruining the wedding . Marge is still a housewife , Bart ( now 25 ) works as a successful building demolition expert , Maggie is a teenager who wears a necklace with her pacifier attached and apparently never shuts up ( although each time she opens her mouth in the episode , she is interrupted ) and Homer still works at the Springfield Nuclear Power Plant in Sector 7G , with Milhouse as his supervisor . Lisa and Hugh travel to Springfield , where Lisa is worried that her family will embarrass her . Things get off to a bad start when Bart and Homer accidentally set the British flag on fire , which they extinguish by throwing it on the ground and pouring compost on it .
