Don't believe us? Just watch.

In a new promo for the upcoming episode of Saturday Night Live, Emily Blunt can't help but crack a joke about "Uptown Funk," Bruno Mars' megahit collaboration with Mark Ronson. But we get the feeling he's heard this one before.

Blunt will be the host and Mars the musical guest on the next episode, premiering at 11:35 p.m. ET Saturday on NBC.
