Chewies grandpa from the christmas special.
I believe that guy was named Itchy? Yikes.
My favorite bit part was either Bossk or Wilrow Hood.
Speaking of bit part Star Wars characters, you should all check out the podcast Star Wars in Character. It's devoted to the minor characters of the movies.
The 4 hosts are hilarious, don't take themselves seriously, despise the prequels, and do a great show. They each work on other podcasts as well, Trailer Pod Boys (about the Trailer Park Boys), The GR80's about 80's movies, and a few others. They all grew up together and all worked at the same movie theater in high school. Strongly recommend their Star Wars stuff!
