You know you’re getting older when it seems like nobody on Twitter knows who Billy Crystal is. Yeah, you read that right. Loads of people (and by people we mean out-of-touch teens) took to the Twittersphere after seeing the opening of the 2012 Oscars with utter confusion as to who the iconic actor is.

‘Princess Bride?’ ‘When Harry Met Sally…?’ ‘Analyze This?’ Ringing any bells?

We’re hoping this is just a silly joke gone terribly wrong. But just in case you were actually staring at your TV with no clue as to who this man is, know this — all those ‘Family Guy’ lines, like “I’ll have what she’s having,” come from movies Billy Crystal helped make famous.
