The Undertaker takes the 'ALS Ice Bucket Challenge'

In a rare public appearance, The Undertaker (real name Mark Calaway) took the "ALS Ice Bucket Challenge."

Calaway took part in the challenge alongside his wife Michelle Calaway (former WWE superstar Michelle McCool).

Calaway rarely makes public appearances outside of his famous character in an effort to keep the mystique and lure behind it alive, but decided to do so, albeit with very dark lighting, to support a good cause.
