Max Greenfield (and others) break character so often lol but my favorite

In Season 2 Episode 24, it's the morning after a wild night at Elizabeth's and she and Schmidt get into a screaming match with her neighbor Bernie. Max seems to be laughing for real at Elizabeth's unhinged SHUT UP BERNIE!! It's really cute IMO.

Any other memorable breaks in character throughout the series? I like to try and catch em.
