A Night at the RoxburyGoofs
After Steve (Will Ferrell) and Emily (Molly Shannon) get engaged, Emily starts putting several of Steve's possessions in a cardboard box to throw away (his going-out clothing, a disco ball, etc.). Emily also grabs his silver chain necklace, tears it off, and throws it in the cardboard box with the rest. Steve then has his necklace on shortly thereafter.
On their way to their father's "fake plant shop", the Butabi brothers pass the lamp shop on their left. This shop is supposedly right next to their father's store (to the left), yet they keep walking for a few more minutes. Then we see them walk into their father's store coming from the right, when they should've walked in from the other direction.
