British Actors Can't Stop Laughing As They Read Their Scene With American Accents

"But dad!"

"I think one of the things that I suspect makes the show so alluring, and seem in some ways like a fairytale to us in the United States is just how plummy all your accents are," Stephen Colbert tells cast members from PBS Masterpiece's "Downton Abbey." 

Michelle Dockery, Hugh Bonneville and Allen Leech, guests on "The Late Show With Stephen Colbert" this December, sat down with the host to try out an amusing little experiment.

Colbert proceeds to hand the cast actual lines from their show — but rather than read in their British accents, the actors reenact the scenes with American ones.

From there on out, the whole scene changes (arguably for the worse). 

"I know we are the only the caretakers of Downton, but dad, some things have to change," Dockery says in a well-done American accent

Throughout the scene, the entire cast, and audience, can't help but laugh. 

There's something about playing with accents that never ceases to amuse — in September, a video of Dakota Johnson practicing Southern, Boston, Australian, and French accents raked in nearly two million views. 

And in 2010, Ben Affleck acted out a bunch of different accents for Ellen DeGeneres to guess, purely for entertainment purposes.

The below is no exception.
