Watching 1999 Christmas episode, and came to the conclusion that I haven’t seen anyone act in roles as physical as Chris Kattan does. While many actors roles in the cast are filled after they leave (ie a new or younger cast member starting to play the same roles that a past, usually successful, member used to typically play). Chris Kattan often plays monkeys and animals, holding on to people. Not that this necessarily an essential role, but I haven’t seen anything like it since.
