Hitchhiker's Guide to the Galaxy, The Easter Egg - Hidden "42's"

As you watch the movie, or read the book, you know that the computer, Deep Thought, identifies the answer to Life, the Universe and Everything as "42". As you watch the movie you can pick out a bunch of hidden "42's" in it. I've caught three but I am sure there are plenty more. One, the movie is approximately 1 hour and 42 minutes long (usually rounded up two 1:50 but meant to be 1:42). Two, when the demolition workers are destroying Arthur's house you can see a newspaper refering to the Dolphins at the begining of the movie and beneath is the number 42. And finally, on the back of Zaphod's cereal box is a message. It goes like this "The perfect breakfast cereal FOR TWO!" That's all my friends and I caught, but keep a sharp eye out for more.
