Continuity: When the family is getting into the car to go to the wedding one grandmother says to the other "let me in". The grandmother gets out to let the other grandmother in but the first grandmother never gets back in the car, she just pretends to. You can see her hiding behind the cars as it backs down the drive. Both grandmothers are in the car when they see Long Duk Dong on the lawn.

Other: The chunk of hair that Ted has in the car is in a ponytail, and much longer than the hair cut off in the door.

Continuity: They make the point that Ted can't take the prom queen home in Jake's car because he does not know how to drive a stick shift (Jake's Porsche) so Ted takes her home in Jake's dad's Rolls-Royce. Later in the movie when Jake shows up at the wedding, you can see that the Porsche is an automatic as he shifts it into drive.
