If you need some tips on tricking out your house this Halloween, check out HGTV's "Halloween Block Party" special tonight at 8pm.

The show follows three families as they decorate their houses by theme: The Haunted Mansion, Hansel and Gretel, and The Legend of Sleepy Hollow. The familes are aided by decorators Michael Russo, Kelley Moore and Eddie Ross.

HGTV will heavily promote "Trick-or-Treat for UNICEF" during the program, and any donations made to UNICEF through the HGTV website starting today through October 31, will be matched by Proctor and Gamble.
