Don't bother checking for a pulse.

The ratings are in for the UFC on FOX 5: "Henderson vs. Diaz" network television event, which emanated from the KeyArena in Seattle, Washington on Dec. 8, 2012, and they are the cause for high-fives throughout the ZUFFA front offices.

When all was said and done, the "Emerald City" extravaganza pulled in 4.4 million viewers for a 2.5 household rating, finishing as the number three show for the week among males 18-49 while winning the night among males 18-34, males 18-49, adults 18-34 and adults 18-49.

UFC President Dana White gloats to Yahoo Sports:

"We just killed it. We killed it in every demo. There are always going to be older people home watching TV on a Saturday night, but the advertisers are trying to reach that demo and we just dominated it. That was a huge night for us."

Fatality!

The main event featuring Ben Henderson defending his lightweight title against Nate Diaz peaked with 5.7 million viewers and the broadcast overall placed second among FOX televised cards, a close second to UFC on FOX 2, which averaged nearly six million eyeballs.

The headlining bout for that card was Rashad Evans vs. Phil Davis and took place at the United Center in Chicago, Illinois, the same venue that will host UFC on FOX 6 next month with Demetrious Johnson vs. John Dodson for the UFC flyweight title at the helm.

Can "Mighty Mouse" save the ratings day? Or will "The Magician" make them disappear?
