The teams had been decided--J.Lo and Fallon vs. actor Anthony Mackie and comedian Steve Higgins--and J.Lo was already bummed that she and Fallon didn't get to start the game.

"Ah, why does he get to start?" she lamented. "Because, trust me," Fallon responded. Already, the game is heated as it turns out that Mackie also doesn't like to lose. 'I had to get rid of Taboo in my house," he said. "I start some fights."

J.Lo, dressed in a pink dress, was jumping around throughout the game and her excitement never wavered. While she didn't win the game, she kept the guys, particularly Fallon, distracted when trying to act out the phrase Bottom Line as she pointed to, well, her bottom.

As the game came to a close, Fallon finally figured it out. "That was the best round of the game that I've ever played in my life," he said.
