Did you see this last night?  Max Wilford is an adorable seven-year-old boy battling a rare form of brain cancer.  His classmates and principal are trying to make the world’s longest Rainbow Loom chain in his honor!

On Wednesday, Jimmy Kimmel joined the cause, inviting Wilford to appear 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 the little patient.

Grab the Kleenex.  Even Kimmel got a bit choked-up at the end...
