Actor Wil Wheaton made another comic appearance on THE BIG BANG THEORY last night. However, that's a far cry from his steady employment back in the days of STAR TREK: THE NEXT GENERATION, which he eventually interrupted to attend college. Today his net worth is just $2.5 million. More proof that college isn't everything if you have a good thing going. But, Wheaton continues to write and manages steady appearances in films and TV though. But, so far that big break since STAR TREK is yet to come.
