I have just spent 5 minutes trying to get this damn printer to print an envelope without mangling it. Wonderful.

This DVD is one of my all time favorite musical DVDs. Miss Jackson proves why she is the highest paid singer in the industry. With a combination of costume changes, great choreography, Janet's greatest hits, and a sold out crowd at Madison Square Garden, the DVD makes for an excellent night of entertainment. I only regret that I was not able to see the concert in person here in my home town due to a cancelation of the concert;however, the DVD is definately a suitable substitute. I highly recommend this DVD to any fans of Janet, lovers of music, and owners of quality DVDs.

As far as I'm concerned the most important holiday every year is Academy Awards night, with the second most important being the day the nominations are announced. Obviously, the Academy Awards are my life and Inside Oscar is my Bible. No matter what page you open this book, you'll be totally drawn and completely forget about time. If I had one complaint it's that too much time is spent on recent years while earlier decades are given less attention. Still, it's such a wonderfully written book, so catty and bitchy, but all in fun; I can't wait for the next edition and find out all the shenanigans involving Titanic and how it's possible Helen Hunt beat Kate Winslet....
