Dad dresses up as Spiderman and jumps off roof for terminally ill son's birthday

Now that's commitment.

Over a year ago, Jayden Wilson was diagnosed with a Grade 4 Brain Stem Tumour and, sadly, his family have since been told it's terminal.

So for Jayden's 5th birthday, his dad, Mike Wilson, wanted to make it very special.

Not only did Mike dress up as Spiderman (or, more correctly, Spiderdad), he also made a pretty spectacular entrance.

All for Jayden's enjoyment.

Good work, dad. And nice American accent!

Jayden's family are currently raising money for immune-boosting treatment - visit the fundraising page here.
