Lamar Odom & Khloe Kardashian -- We Got a Mouth to Pee In, Too!

The Rolling Stones memorabilia museum in Germany isn't the only place in the world with giant mouth-shaped urinals -- Lamar Odom and Khloe Kardashian got one too ... and TMZ has a pic!!!

As we previously reported, several women in Germany are pissed over the lippy whiz receptacles in the German museum -- claiming they're demeaning to women -- but the museum owner is refusing to remove them ... because they're damn expensive.

But according to sources, Khloe and Lamar's urinal isn't so lucky -- and will be getting the heave-ho in the near future as part of a remodeling project in their Tarzana, CA home.

We're told it has nothing to do with how offensive the urinal may or may not be -- it just doesn't fit with the new decor ... so it's gotta go.
