Oh, about that! Peyton Manning was just as amused by his brother Eli Manning's, um, interesting reaction to the Denver Broncos' Super Bowl 50 win over the weekend.

As football fans know by now, the Giants quarterback, 35, appeared sad when his older brother Peyton, 39, beat the Carolina Panthers 24 to 10 in Santa Clara, California, on Sunday, February 7. As the rest of the Manning family cheered, Eli stood in the back with a stoic, almost sad expression that captivated the Internet.

"Eli and I have always supported each other," Peyton explained during The Tonight Show Starring Jimmy Fallon on Thursday. "I think Eli is analyzing the game and the end of the game kind of like how I would as if he was playing it. And so he was just as happy."

Peyton laughed off his younger sibling's reaction. "But it's funny. When I saw that clip, Jimmy — I've seen that look before," he continued. "I recognized it. In other big moments in my life he's had that expression."

And with that, the two men decided to spoof the hilarious moment. Fallon, 41, pulled out a cardboard cutout of Eli's reaction and the two men spoke to it.

"Eli, I got us front row tickets to Adele!" Fallon said, as Eli's cutout stayed put. Peyton joked: "Eli, Ashley [Thompson] and I are expecting twins. You're going to be an uncle!" (The couple welcomed son Marshall and daughter Mosley in March 2011.)
