My son and I like to quote the movie cars.  I will usually start it and he will finish it.  Between the two of us we can quote quite a bit of the movie.  We usually have one that we do quite a bit for a while, then we move on to a different one. The most popular one lately is when Lightening McQueen is saying '1 Winner, 42 Losers, I eat losers for Breakfast".  The best part of it is that my son can't really say the word "Breakfast" it comes out as "Breatpast". I love being a Dad.
