Very few actors break big in their first starring role — but their years of slogging through small TV parts can be a huge boon for fans, who get to enjoy watching them before they were stars!

COZI TV understands this mentality perfectly, and this Thanksgiving is giving us a few dozen reasons to be thankful — with a four-day back-to-back marathon of classic TV episodes showing some of our favorite actors in their earliest roles.

(Nevertheless, we're quite sure fisticuffs occurred at some point.)
