He's got a message for Vladimir Putin!

Lena Dunham may have been this week's Saturday Night Live host, but Liam Neeson nearly stole the show from the actress-writer when he made a surprise appearance during the sketch comedy's cold open.

The Irish actor responded to a call for help from Barack Obama (Jay Pharoah) after the president's conversation with Putin regarding Russia's invasion of Ukraine "did not go well."

Neeson channeled his CIA agent character from the hit 2008 action-thriller Taken to send a message to Putin and his troops.

Hilarity ensues – including a demonstration of Obama's newfound scare tactics – and reminds us all why we love Neeson, who's not afraid to poke fun at himself!
