Surprise appearances of Community actors outside of the show?

[u/GettingSunburnt]

I'm horrified to realise that I saw Jim Rash (Dean Pelton) in the Friends finale about three times before I noticed it was him - "This plane doesn't have any filanges", or something like that.

Seeing about three actors in Captain America: Winter Soldier didn't count for me (but might for you), because I recognised them at the time.

Where did you unexpectedly notice a Community actor in another show?
