This was a romantic getaway that George and Angie took some time in the past. It is referenced twice - once when George was about to show Angie her video tape birthday present when Angie said "George, is that the tape from our weekend at the lake because the kids can't see that!" The other time was when Angie was imitating how George was licking a sandwich and asked him "remember this?" to which George replied "how could I forget our weekend at the lake?"
