The only monster here is the gambling monster that has enslaved your mother. I call him Gamblor, and it’s time to snatch your mother from his neon claws!— Homer
This is a very regular occurrence on The Simpsons: quick voiceovers at the end of commercials or television programs seen on the show. Here's a complete list of them, including the episode they were in.
A commercial for the lottery begins this episode:

Voiceover: Actual odds of winning one in three hundred and eighty million.
An I&S Movie advert:
Voiceover: Fifty-three percent new footage.
A commercial for Truckasaurus: The Movie is shown, apparently featuring
Marlon Brando as the voice of Truckasaurus. But...
Voiceover: Celebrity voice impersonated.
Next, Homer watches a commercial for Lanley Institute of Monorail Conducting,
which shows a photo of a big official-looking building...
Voiceover: Actual institute may not match photo.
A commercial for Duff Gardens shows Lance Murdock riding on a rollercoaster...
Voiceover: To be completed in 1994.
...and Lance falls off the edge!
Krusty: Every time you watch my show, I will send you forty dollars.
Voiceover: Cheques will not be honoured.
After an Itchy & Scratchy cartoon, the following message appears on
screen, with the voiceover:
"The preceding cartoon contained scenes of violence and should not have been viewed by young children."
The end of a commercial for tickets to the big game:
Voiceover: Warning: tickets should not be taken internally.
Homer adds: "See, because of me they have a warning."
Bart sees an advert for Itchy & Scratchy cells:

End of the Mayor Quimby campaign commercial:
Commercial: Quimby. If you were running for mayor he'd vote for you.
Voiceover: Paid for by the "Mayor Quimby for Mayor" Mayoral Committee
A Sideshow Bob commercial:
Commercial: Mayor Quimby supports revolving door prisons. Mayor Quimby even released Sideshow Bob, a man twice committed of attempted murder. Can you trust a man like Mayor Quimby?
Voiceover: Vote Sideshow Bob for Mayor.
When Homer appears on Rock Bottom, the footage is edited to make him sound
like a pervert. Then while a still picture of Homer is displayed on screen...

people and landmarks.
