Marshall's quest for the perfect retreat for some restroom reading is proving to be the biggest tabloid magnet since three-headed alien Elvis babies.
On the heels of the news that Hills belle Heidi Montag and her beau, Spencer Pratt, will be guesting on How I Met Your Mother comes word that Kim Kardashian will be butting in on the action.
The set-up for the January episode: As Marshall scours his office building for a potty that offers a gent proper privacy, the cover subjects on his mag of choice — "Them Weekly" (har!) — speak to him from their glossy confines.
The episode tapes this week, in between sessions of Speidi posing for "candid photos" in the park with a dog.
