Now that cannabis is finally legal in the state of California, late night hosts have had a bountiful harvest of new material. And no one has gotten more out of it than Jimmy Kimmel: his "Who's High?" segment is now a regular bit. It's a simple setup - Cousin Sal hits the streets, finds two non-high people and one high person, and Jimmy has to guess who's been partaking. In one case it's not immediately apparent. In the other, it very much is. Click play on the video above and see how you do. 

(Also - great call on having Girl Scout Cookies as a prize.)
