A Pillow Joke

a joke about the pillow. :) the wife was sleeping and get up during the middle of the night, and ask her husband if he can get more pillow because his wife want more so feel comfortable. so her husband went outside and to his truck to get extra pillow in his truck, but turn out, he can't find his home, because all of the window is same and the shape is same, so he got an idea to make some noise, then it worked, found his home by how? one light is not on while all of the lights is on, lol. enjoy!
