Man vs. Wild returns with a new season on Wednesday, January 12 – and it doesn’t fail to bring the gross. Watch this video clip of Bear Grylls’ trip to Panama, where he gives himself an enema to help with hydration.

The video clip of Bear Grylls’ enema reads: “The following segment contains material that may be disturbing to some viewers and contains partial nudity.”

Consider yourself warned.

In the episode, Bear also eats a fish eyeball (roly poly fisheyes, anyone?).

The press release for this season’s Man vs. Wild will have Bear Grylls traveling to China, Montana, Guatemala and Poland, climbing a huge waterfall, landing on an active volcano, and more!
