It's 5pm on the West Coast, and you know what that means: it's time for the official end-of-monday horse-tuck video.

That's right, everyone. As you all know, this video of Rumba the Wonder Horse tucking himself into bed is the official signal that the Monday workday is over. This is the Internet equivalent of hearing the Flintstones horn on the wacky drive-time radio station. Stay tuned on Friday for the video of Rumba headed to the bar and falling asleep as his coworkers tell boring stories at happy hour.
