WWE legend The Undertaker and his wife, known in professional wrestling as Michelle McCool, had a terrifying experience near crystal clear water on Sunday afternoon.

McCool, whose real name is Michelle Calaway, posted several videos on her Twitter account showing a nurse shark swimming in the shallow water where she was. She said that she called her husband to come check it out.

The Undertaker, whose real name is Mark Calaway, stepped into the water and, standing at 6-foot-10, leered at the shark. The shark would swim away when the «Deadman» entered the water.

«I was just enjoying a book on the beach when this ‘vegetation’ looked so much like a shark,» McCool tweeted. «So I texted my husband @undertaker… like I really liked that last photo.»
