On a recent episode of The Tonight Show Starring Jimmy Fallon, Cardi B had the audience in stitches as she took on the iconic game Box of Lies.

The rules sound simple but are trickier than they appear: each player picks a mystery box, shows the object inside only to the audience, then describes it (truthfully or not) to their opponent. The opponent must then guess if it’s the truth or a lie.

Right from the start, Cardi B stole the show when she struggled to describe the strange item in her box. After a moment’s hesitation, she blurted out the words “pussy balls,” sending Jimmy Fallon and the audience into uncontrollable laughter. Her quick wit and unfiltered humor instantly turned the moment into a viral-worthy highlight.

Not to be outdone, Fallon picked another box and made up a story about “a wrinkly dog dressed in a Freddy Krueger outfit.” Cardi fired back with the punchline, “Sounds like my ex-boyfriend’s grandmother,” sparking another explosion of laughter from the crowd.

By the end of the game, Fallon admitted defeat, conceding victory to Cardi B’s charm, wit, and unbeatable sense of humor. It was a “Box of Lies” showdown that fans will be talking about for a long time.
