Yelling aficionado Billy Eichner is very good at getting celebrities to roll with him on his quests to rattle New Yorkers of all ages. Everyone from an apologetic David Letterman, to a speed caroling Amy Poehler, to master thespian Julianne Moore have spent time running around Manhattan with Eichner for his show Billy On The Street. And this time out, he got "King of Christmas" Will Ferrell to help him quiz people about holiday movies, hand out dollars to petrified strangers, and argue the value of giving out replica bales of hay as presents.

We should probably add "a pajama-clad Billy Eichner yelling 'Scrooge! Scrooge!'" to the list of quintessential NYC moments.
