America's ABC television network says it will air four holiday-themed "Extreme Makeover: Home Edition" specials, starting next month. Author and television personality Jenny McCarthy will be the guest host of the Thanksgiving episode to premiere Nov. 26. The remaining three episodes will air on the following three Mondays -- Dec. 3, Dec. 10 and Dec. 17. Do-It-Yourself guru Ty Pennington is to serve as host of those programs. "Extreme Makeover: Home Edition," a show in which Pennington headed up projects to help deserving families improve their housing, aired on ABC from 2002 to 2011.
