Texas Dad dances outside a children's hospital window for son

A Dad in Texas has gone viral after he was seen dancing outside a children's hospital for his son. His 14-year-old son Aiden has leukemia, and goes in for chemo every week.  But only one parent can go in so his dad stands outside his window in the parking lot and dances like an idiot, just to keep him entertained.  What a great parent! This guy is the best!
