The incarcerated contestants of the Big Brother shows never get to enjoy random backyard visits from celebrities like Doogie Howser aka Neil Patrick Harris, who stopped by the other day. What viewers never get to see are the house’s ceilings. We like ceilings so much, you could call us a ceiling fan – ba dum bum. But what nobody should see is the Playgirl spread of Big Brother 5‘s aptly named Scott Long, which we warn you is NSFW. Scott was back at the house to help with a challenge that will probably be on tonight’s installment of Big Brother: All Stars.
