I always get a big laugh out of impersonations, especially impersonations of people that are difficult to impersonate. On Late Night With Jimmy Fallon, his guest was actor Benedict Cumberbatch, and Fallon found out that Cumberbatch does the best impersonation of Alan Rickman, who was a guest on the show earlier in the week.

For those of you who do not know who Alan Rickman is, first of all, SHAME ON YOU! Just kidding, but really, he is famous for his roles as Hans Gruber in Die Hard and Professor Severus Snape in the Harry Potter movies.

Jimmy Fallon said that he does a good Rickman impersonation, so he challenged Cumberbatch to a 'Alan Rickman-off'! Watch and laugh!!
