January Jones and Jimmy Fallon Shoot Arrows as Cupids on 'Late Night' (VIDEO)

January Jones and Jimmy Fallon dressed like Cupids in honor of the Valentine's Day holiday and held an arrow-shooting competition on 'Late Night' (Weeknights, 12:37AM ET on NBC). And by dressed like Cupids, we mean they put on fake wings.

But the arrows were real.

Actually, no they weren't. They were like something out of Green Arrow's arsenal. Each had a tiny plunger on the tip, so it could stick to the points board. It's a good thing too, as this was also a drinking game.

They could either hit hearts with point totals in them, or broken hearts, which would mean they'd have to do a shot of champagne.

"Yeah, we're going to do shots of champagne," Fallon confimed when Jones started laughing. "I'm very classy."

As it turns out, Jones was going to do shots of champagne, and she was also going to get all of the points. Fallon couldn't even consistently get his plunger arrows to stick to the board.

"I think the champagne helps," Jones said after nailing 25 points. Unfortunately, by the time Fallon decided to cheat and drink some to try and improve his game, she was up 35-0.

We're just impressed they got through the game at all. Jones proved herself every bit as bad as Fallon at cracking up, and they spent as much time doubled over in laughter as they did actually taking aim.
