You can make all the jokes you want - the Oprah Winfrey show is a great show to watch when you are eating that snack in the afternoon after your workout and just need a cool down.
Although the Oprah Winfrey show is often times related to women or things that women do or buy, I find that, as a guy, one can learn a lot not only about women themselves, but about other things concerning the world. Most of the topics on the Oprah Winfrey show are not even tear jerkers at all, but rather informational and usually world oriented and very interesting.
The Oprah Winfrey show is usually on in the afternoons for me, though it could be on at different times depending on where you live. If you love to rent, I would suggest getting the DVD of some of the episodes - you can rent it or buy them off of her website at www.oprah.com
So, don't be afraid of the Oprah Winfrey show - give it a shot and get in touch with your feminine side. Who knows, maybe you and your girlfriend will now have something to talk about at the dinner table.
