Watch Rob Gronkowski and Marshawn Lynch Fight to the Death on ‘Conan’

Two men enter, one man leaves. Those are the stakes when you play Mortal Kombat, and Marshawn Lynch and Rob Gronkowski got a taste of that when they faced on Conan O’Brien’s show.

O’Brien often get celebrities to try out new video games before they hit the market on his show. Since Mortal Kombat pits otherworldly beasts with superhuman strength and powers in a fight to the death, it was the perfect game for Gronk and Lynch.

First, we got a look at our fighters.

Bite Strength: 4,000 pounds per square inch.

Favorite Gilmore Girls Character: Lorelai

The Mortal Kombat fatalities were as gruesome as ever.

And suddenly Beast Mode wasn’t so beastly.

Then again, Conan couldn’t handle it either.

Gronk was his usual self, making fun of Lynch’s patented touchdown dance…

…and finding an alternative use for the Mortal Kombat trophy.

Overall, it was a fun diversion before the real battle takes place on Sunday.
