William Shatner is 80 years old and a legend. He's so iconic, he's surpassed any of the famous characters he's played and become a character himself. That pretty much means he gets to do anything he wants, which is exactly what happened on 'The Late Late Show' (Weeknights, 12:37AM ET on CBS).

He's also so nice and charismatic, you kind of want to do whatever he wants. Which is how you can explain Craig Ferguson getting down on all fours on the set with William Shatner riding him like a horse, teaching him different gaits.

"I thought you made a beautiful horse," Shatner complimented Ferguson afterward.

It was good for Ferguson, too. "I have to say, I feel more alive than I've felt in a long time."

Ferguson then went on to say that he suspected the whole experience was more entertaining for Shatner than it was for Ferguson or even the audience, but we think he underestimates the entertainment value of Shatner riding on a man's back. That's comedy gold right there!
