Lena Dunham Almost Got Arrested At The Airport

Lena Dunham dropped by “Late Night” on Thursday, Feb. 27 and shared a recent airport experience that she’d like to forget.

Thanks to a self-defense keychain one of Dunham's co-workers had given her, a TSA agent got suspicious and made her wait 45 minutes for law enforcement to arrive.

“They like look at my passport. They’re like, ‘Len-uh Durham?’ And I was like, ‘Mmhmm.’ That’s me.” Dunham said.

“I was like, they’re gonna Amanda Knox me. I’m gonna go away for a long time," she continued. “I was like, this is like, ‘SVU’ times a thousand. I was crying.”

Eventually the agents let her go, but only after she agreed to hand over the keychain. She had no problem with that ... but she did miss her flight.

Lena said the only thing that got her through the incident was thinking, “This might be an okay talk show story.”

An okay talk show story indeed, Lena.

"Girls" airs on Sundays at 10 p.m. EST on HBO.
