After the guys are finished watching the mower convention commercial it shows Boomhauer sitting on the floor next to Dale, but earlier when Dale was talking to the girls in the kitchen, Boomhauer was not there.
There are a couple of shots where you can see the Boggle letters in the final round and there is no way that ANY of the words that were said would be on the board, especially the one Peggy won with.
When Peggy walks in to the first game she doesn't have any of her items with her but when she sits down all her things are already on the table.
When Boomhauer is trying out the virtual tractor, there are wheels on it. But when Hank tells the guys that he needs to help Peggy, the wheels on the tractor disappear.
While in Elks, Peggy is playing Boggle and Hank came up to her saying that he is ready. When Peggy says Ho-Yeah, notice the girls in the background still holding the boggle box, frozen.
(Peggy is crying after losing a game of boggle)
Hank: You're smarter than anyone in Arlen.
Peggy: Well, woopty-doo, I'm the smartest hick in hick town.
Hank (about Dallas): That place is crawling with crackheads and debutantes, and half of them play for the Cowboys!
(To Peggy after she lost)
Hank: You loser! You just a big ol' loser! Go ahead and cry, baby! Baby want a bottle!?
Luanne: Can I go back to bed, Aunt Peggy? I got to get eight hours of beauty sleep and then write a paper on it.
Luanne: Boy Aunt Peggy, the words I don't know could fill a dictionary.
Peggy:(entering the Boggle Tourney) Hank, I have been waiting for this moment ever since I reached ages eight and up.
(After losing $13 to Peggy at Boggle)
Minh: Thank you for Boggle lesson, Peggy Hill. Maybe next weekend I teach you mah-jongg. Bring your checkbook!
Bill: I feel like the pretty woman.
Pretty Woman is a 1990 film staring Richard Gere and Julia Roberts about a prostitute.
Bobby mentions Home Depot. Home Depot is a hardware store.
Dairy King is the name of one of Peggy's boggle sponsors. This is similar to the food chains Dairy Queen and Burger King.
The scene when Bobby slides across the floor in his underwear to the Bob Segar song "Old Time Rock And Roll" is a parody of the scene in Risky Business when a young Tom Cruise dances to the same song in his underwear while his parents are out of town. Just to emphasize the similarity, Luanne is watching a rented video of Risky Business when Bobby slides into the living room.
