Seriously, if someone tries to repeat this in real life to you, you're allowed deck them.

Fallon is once again pushing his 'Lip Sync' brand, arguably the only successful contribution he's made to pop culture in his time as host of 'The Tonight Show', this time enlisting pop star on the up and up Ariana Grande.

Grande can barely get away (or sincerely commit) to the sketch but Fallon's overacting and lip syncing are painful to say the least. We can't allow this to become a thing.
