UB's glasses keep disappearing and reappearing while enjoying the girls' catfight in the shower.

When Sistah Girl is at UB's apartment, he begins unbuttoning his shirt. After she hits him, one extra button is rebuttoned.

The "Catfight" between Sista Gurl and White She-Devil. When White She-Devil hits the shower knob to turn it on, she turns the knob down. But throughout the shower scene, it stays in the middle, neither up or down.

The helmet of White She Devil changes during the motorcycle chase: in close-ups it is a more open model so you can see her face, in wide shots the helmet covers her face (presumably to obscure the use of a stunt double).

In the opening sequence, the amount of orange soda in Undercover Brother's Big Gulp changes from full, to half-full, to tip-top full again.

At the golf course, right after the security guards' golf cart comes into contact with the propane pipelines, it is clearly seen before the explosion that the passengers are actually dummies.

She-devil's henchmen's motorcycles are both stock 2002 Honda CBR600's but when one of the bikes crash to the wall and explodes it is a circa 1997 Kawasaki ZX-6R with clearly visible stunt equipment (special tires, handlebar) fitted and the rear fairing painted to look like a Honda CBR.

When she-devil and her henchmen take off to the chase and are starting their motorcycles, the instrument cluster shown (a circa 1995 Honda CBR600) doesn't match she-devil's (1997 Kawasaki ZX-6R) or her henchmen's (2002 Honda CBR600) bikes.

When UB's license plate slides away to reveal the nozzles, Toronto's distinctive CN Tower is clearly visible in the background. Undercover Brother's city is never named, but it is supposed to be American.

When Lance asks Undercover brother about the show Friends (1994), he asks what Ross saw of Julie's in the third season. This happened in the second season, Julie was not on Friends in the third season. He also calls her Julia instead of Julie.

As the B.R.O.T.H.E.R.H.O.O.D. team infiltrates the Man's compound in the "Island Fortress Cleaning Service" van, Dave Chappelle's tongue is green. Evidently he had been sucking on a piece of candy just before the scene was shot.
