E! has confirmed that the demonic blond duo from The Hills Heidi Montag and Spencer Pratt will be joining the cast of How I Met Your Mother for an episode.

Fittingly enough, the storyline revolves around Marshall (played by Jason Segel) attempting to find a bathroom at work where he’s comfortable enough to go number two.

The two-dimensional couple will play magazine versions of themselves on the cover of Them Weekly. As if any other versions of them actually exist.
