This slip up occurs when Adam Sandler's character is outside his house smoking a cigar and the neighbor boy rolls up next to him on rollerblades.

The neighbor boy starts talking about his new RV when his mother comes outside and makes a comment to Adam's character about smoking cigars. He then tells her that he found her boy smoking it.

When the mother yells at the boy to get into the house, he turns and runs into the home.

If you are paying attention to the scene, you can easily tell that the boy would have had no time to take off the rollerblades, put on and tie his shoes.
