King of The Hill

In the courthouse scene when Dale has himself on the witness stand, the red and white stripes of the U.S. flag shift from being correct to incorrect several times. The correct U.S. flag from top to bottom starts and ends with a red stripe never a white one, also the first stripe below the blue union is a white one not a red stripe.

The Canadian flag parodies the logo of a famous (M) cigarette brand whose actual logo resembles the signal code flag design for the letter B (Bravo) in the International Code of Signals. Vessels display it to indicate I am taking in, or discharging, or carrying dangerous goods. Manitoba (MB) is a Canadian province with no special tobacco link, however, the printed word Manitoba has a certain look. Manitoba lends its name and Canada flag connections to King of the Hill's fictional Manitoba Tobacco Company and its fictional corporate items worn by Dale in this episode. Dale even replaces his usual Mack Truck ball cap with one from Manitoba.

The mounted salmon which was used to bug Dale's home is a spoof of Big Mouth Billy Bass an actual product sold mainly by direct mail. It was motion activated and would wriggle and play one of several songs. Don't Worry, Be Happy was one of the actual songs as parodied by Smoking Sammy Salmon here.

The face cream Luanne gives Nancy is a La Leche del Sol (Milk of the Sun) product. Luanne goes to great lengths to acquire the beauty product in Mexico in the second season episode "Three Days of the Kahndo."
