Watch What Happens When Robert Downey Jr. Gives This Kid A Bionic Arm

In Iron Man 3, Tony Stark had to spend some time with a precocious little kid, but it was no match for the real-life interaction between Robert Downey Jr. and this bowtie-wearing boy.

RDJ teamed up with Albert Manero - founder of the non-profit charity Limbitless Solutions, which produces affordable bionic limbs - to give seven-year-old Alex Pring the gift of a lifetime.

Born with a partially developed right arm, Alex is invited to a hotel room to meet "another bionics expert," revealed to be Downey Jr.

Alex, of course, just knows him as 'Robert'.

Watch the video of Robert and Alex comparing their brand new Iron Man arms and have your heart warmed, if not entirely overheated.
