Brian comes over to Annie's house and goes up stairs, saying he forgot his shoes.

When Brian first comes over to meet George and Nina he has his hands on Annie's leg. Later in the same scene Brian and Annie get ready to leave her parent's house and while saying goodbye George says "don't forget to fasten your condom." What he's actually trying to say is seat belt.
