Tom & Jerry (Chuck Jones era) S01E05 - Snowbody Loves Me

Jerry is out in the cold Swiss Alps during a snowstorm, caught up in a snowball and rolls all the way into a pillar as the title card and credits are shown.  Jerry then peeks through the window and he sees the cheeses. He raps on the door and wakes up Tom, who promptly opens the door, only to find no one there. He walks out into the cold; however, Jerry sneaked in under the cat and the door closes on Tom.
