What scene did you catch after multiple viewings

I've watched the office A LOT just like most of you.

What's your favorite scene or moment that you never really noticed until later viewings?

Mine is when dwight got the concussion.

He starts going "chugga chugga chugga"

And Jim asks what are you doing?

"Vietnam sounds"

Idk why but after noticing it after 10 years of watching, it's my favorite part of that episode now
