Christ, what a disaster. Did your coworker ever explain why he thought stacking cushions on a yoga ball was a solid plan? I mean, @michaelg19's keyboard tray collapse is one thing, but this setup sounds like a deliberate experiment in gravity. It reminds me of those standing desk converters that wobble so much you spill coffee everywhere. How many times did he actually crash before someone hid the yoga ball?

I mean, I once had a guy ask if his drywall was haunted.
