Two of Marvel’s three actors named Chris are heading to battle, but not on screen. Chris Evans and Chris Pratt had an epic Twitter exchange on Tuesday, which finished with the two betting on who will win the Super Bowl.

Evans, who plays Captain America, egged Pratt on, noting that their favorite teams - the New England Patriots and Seattle Seahawks - are facing each other in Super Bowl XLIX. “For the next 2 weeks, you are not my friend, you are my enemy,” Evans wrote.

Pratt responded by writing that there is only one real Captain America, Seahawks QB Russell Wilson. Evans then suggested a bet and Pratt, who plays Star-Lord in Guardians of the Galaxy, came up with the stakes.

If the Seahawks win, Evans will have to visit the Seattle Children’s Hospital in full Captain America gear, while waving the 12th Man Seattle flag. If the Patriots win, Pratt will have to wear a Tom Brady shirt and visit Christopher’s Haven in Boston.

Now, if only the third Chris, Thor’s Chris Hemsworth, could get in on this somehow.

The Super Bowl is on Feb. 1.
