On last night's 'Extreme Makeover: Home Edition,' lovable cartoon characters Phineas and Ferb lent a hand to the home demolition portion of the show.

But, of course, the boys weren't content with traditional means of leveling the house. Instead, they constructed a massive shrink ray which reduced the home to a tiny version of its former self.

The characters made an appearance in honor of nine-year-old Aniah, who saved her younger sister from getting hit by a car, but lost a leg herself in the process.

Watch Phinaes and Ferb's guest spot and the sisters' priceless reaction below:
