As the New York Rangers played the Tampa Bay Lightning in Game 5 of the Eastern Conference Finals on Thursday night, the talk show host was the focus of attention.
He was seen frantically chomping down a hot dog after dunking it in his drink in front of a rowdy crowd at Madison Square Garden, as seen in a now-viral video on social media.
In the end, he savagely shoved a bread bun into his face, attempting to wash it down with a cold beer.
Fallon's chugging efforts were a subject of scrutiny, however, since he missed his mouth while fans cheered.
An excited fan rubbed Fallon's head after his woeful attempt.
Having accepted defeat, Fallon later appeared in the stands in a Rangers jersey after swapping his beer-stained sweater for something more appropriate.
Fans took to social media to express their laughter about the comedian's fun night out.
One fan tweeted, "That's how you know someone has money. He just dumped 40 bucks on the ground.". Another remarked, "He was destroying that glizzy."
A third responded, "Dipping a gizzy in your beer and then putting it in your mouth is wild behavior.".Last night, it wasn't just Fallon who lost.
As Rangers fans expected, the team lost to Lightning 3-1 in a grueling playoff battle for a Stanley Cup berth.
Immediately following the game, Bolts captain Steven Stamkos and Rangers forward Alexis Lafreniere faced off in front of goalie Igor Shesterkin before dropping the gloves.
As a result, the pair received fighting majors on the scoresheet.
