'Star Wars', the scrappy little sci-fi saga that you may not have heard of, is back this Friday. 

One of the most exciting things about the forthcoming 'The Last Jedi' is the presence of Mark Hamill, aka Luke Skywalker, who will play a significant role in the film. Hamill is a seasoned actor and voiceover artist - but did you know that he gives one hell of an autograph?

A couple of years back, autograph expert Steve Grad shared a series of classic Topps' 'Star Wars' cards featuing Hamill's signature - and his sharp sense of humor. Instead of leaving fans with his signature alone, he takes the opportunity to show off his sharp sense of humor. For example:

vader hamill

smoke hamill

And, for obvious reasons, our personal favorite:
