'Sesame Street' nails mannequin challenge — until Ernie hilariously messes up

/ Source: TODAY

If you thought the mannequin challenge that's taken over social media was starting to wane, that's only because you haven't recently taken a trip to Sesame Street.

In a delightfully silly video posted on Twitter on Tuesday, a camera travels up and down a frozen, silent Sesame Street, capturing all kinds of frozen moments between Muppets, cast members and crew.

We particularly like the places where they've made it seem truly frozen in time: papers falling, dishes tumbling, egg cartons on the verge of landing on the floor.

And then we circle around to Ernie and Bert, gamely holding their faces still ... except Ernie decides that's the moment to alert Bert of a small detail he's overlooked: his shoelaces.

Bert, ever fastidious, bends down to tie them and ... the moment is shattered.

"It wasn't me!" cries Bert, much to Ernie's (and our) amusement.

Oh, that Ernie!
