Clipperton's suicide
People in the competitive jr. tennis community somehow regarded it as healthy that Mario Incandenza’s perfectly even smile never faltered even through tears at Clipperton’s funeral. […] It took the bradykinetic Mario all night and two bottles of Ajax Plus to clean the room with his tiny contractured arms and square feet; the 18’s girls in the rooms on either side could hear him falling around in there and picking himself up, again and again
Context
Clipperton has blown his own map in Subdorm C, and it's Mario — his one friend — who insists nobody else clean the room. The body at labor: bradykinesia means the job takes all night, the contractured arms and square feet mean he keeps falling, and the girls next door hear him picking himself up "again and again."
