That time a peacock bit Chandler in the finger at the zoo...ever mentioned outside of season 1 again?

It gets mentioned twice in season one (Someone's house, binge-watching date kinda~kinda thing) with enough episodes apart that a casual once a week viewing wouldn't have picked up on.

There's a couple of other things like that too which do turn into major story arcs and elements within the overall show but I can't think of Chandler's finger being bitten being mentioned again.

Does anyone recall if it does, I've honestly not seen it in over a decade and only picked up on this because it was back-to-back breakfast and Bing stuff...
