Max Wilford is a 7-year-old boy battling a rare form brain cancer - his classmates and principal are trying to make the world’s longest Rainbow Loom chain in his honor.

On Wednesday night, Jimmy Kimmel had Wilford on his show, where he donned a special “Suit of the Loom” — which he’s auctioning to benefit The Max Love Project — and brought out IRON MAN to meet Max. (AWESOME)

At the end of the segment, Kimmel choked up with emotion. Can't say I blame him.
