Zac Efron: [Robert De Niro's patience is wearing off] One last thing, with energy, with enthusiasm this time. Can you please light the candles on Sammy's birthday cake?
Robert De Niro: No, I'm sorry, excuse me, but I did the birthday message, I sang the birthday song, I had a lot of energy, it was perfect. So with all due respect, The two of youse can go fuck yourselves. You hear that Sammy? The two of youse can suck my dick!
