WATCH: Saoirse Ronan explains what an Irish pub 'lock-in' is to Jimmy Fallon
Saoirse Ronan taught Jimmy Fallon about Irish pub 'lock-ins' when she appeared on Tuesday night's The Tonight Show.
The topic came up when Fallon told the Oscar-nominated actress about a recent trip to Ireland he has taken with his sister.
The TV host said he couldn't believe that the B&B they were staying in invited the pair to enjoy drinks with the pub owners after closing time.
“The whole town comes into the pub and they lock the door…” a confused Fallon explained.
“Yeah, it’s a lock-in…” Saoirse responded.
