Emily Blunt is hardly the first host to break during a Saturday Night Live sketch but there's something very enjoyable about watching her failing to keep it together on last weekend's show. 

The Girl on the Train star participated in a sketch alongside cast member Leslie Jones where the duo played high class escorts with very unusual methods when it comes to role play.

Said methods included Jones adopting the persona of Family Guy's Stewie (no, seriously) and Blunt playing a clumsy English maid with an outrageous catchphrase - "Oopsie doopsie, I muffed it up again!"

It was that very catchphrase that caused Blunt to break on not one but two occasions.
