"Castle" is a wonderful book for children who have short attention spans. It provides adventure and re-affirms the laws of chivalry.

THIS AIR BED IS GREAT! I HAD PREVIOUSLY PAID WAY MORE FOR THE "A--O" BRAND, BUT THIS ONE IS EVERY BIT AS GOOD AS THE MORE EXPENSIVE ONE. I AM A GAL WITH A "MATURE" FIGURE, AND IT (TWIN) ONLY LOST A LITTLE AIR. WITH THE ELECTRIC PUMP, NO WORRIES! JUST A HINT FOR SOME OF YOU WITH BAD KNEES LIKE I HAVE....I PLACED TWO CAMP COTS SIDE BY SIDE AND LAID THE MATTRESS ON TOP. PERFECT FOR THESE TIRED OLD KNESS AND BODY TO GET UP AND OFF OF. KUDOS ON THIS AIR BED!

Ex Output:
Positive

I am big fan of Judd Apatow's work. i went into this hearing that its not like his other movies, that it has a more somber, serious tone. so my expectations were tempered. I liked it, i do agree with some other reviewers that it was probably a little too long, which is why I take off one star. But if you go in knowing this isnt a 40 year old virgin/knocked up style comedy then you wont be disappointed. with that being said, i can see why some people rated this poorly if thats what they thought they were going to see going in.
