Someone RSTLNeeds to calm down.

The category was "What Are You Doing?" and that's exactly what Pat Sajak was struggling to figure out after a second pair of contestants made a horse-related guess based on only two letters. 

On Monday night's show, it was Best Friends Week, which was filmed in Hawaii. When a pair of men randomly guessed "Riding a brown horse" and not surprisingly got the puzzle wrong, the next two ladies decided to guess "Riding a white horse." Pat Sajak couldn't take it anymore and walked off the set.
