The nodding guy in the ballpark stands

I just got around to watching the episode "Hat Hair" where they're at the ballpark.

The guy in the stands who is nodding enthusiastically at everything Jim is mentioning was perfect. (Cricket, day/month/year, etc.) The guy didn't even have a line and I was laughing my ass off. Whoever came up with that in the writer's room had a gem that day. Perfect execution and still subtle.

Small moment in the grand scheme of things, but I just really enjoyed it.
