Cricket joke

The Devils challenged the Angels to a game of cricket.

"But we've got all the cricketers," said the Angels.

"Yes. But we've got all the umpires!" exclaimed The Devils.

The most strange umpiring decision I have ever seen

I received this youtube link on mail and was shocked to see what happens there. I replayed it again and again to find out whats the matter but am still clueless. Can someone explain whats happening here?
