blonde moment

So, I had a TOTAL blonde moment yesterday. I bought the DVD the 30 day shred. I've heard it is really hard core and a great workout. Well, I thought I will just do it at the gym after my usual cardio on the stairmaster. So, I put the DVD into the play, it was a 5 disc changer and I noticed this. So a DVD starts playing and I am using the remote to find the work out. I noticed that it wasn't the same lady as the cover of the box, but I figured maybe they hired it out. As I am doing the work out I am thinking this is WAY too easy. Well I get home and really start looking at the box and notice that the pictures on the back are not the same as the workout I did earlier. Then I open the box and look at the front of the DVD and I am thinking maybe they switched them and I am going to have to return this DVD...then the light comes on...it was a 5 disc changer and I must have done some random DVD in the changer....DUH!!!!! Really!?! It took me getting home to figure this out! So tonight hopefully I will start the 30 day shred!
