Way back years ago, there was a 62-year old deaf man,
institutionalized for 42 years, employed as a restaurant
dishwasher. Thought to be mentally retarded and dangerous
to society, he was an excellent dishwasher but had a trait
that was annoying to his hearing co-workers, the weirdly
pitched sound emitted while he was laughing on the job.
The vocational rehab counselors discussing his case
were shocked, upon retesting, to find his IQ rated at 142.
They were discussing what to do with him, namely:

1) to let him continue in his job and to try to curb him
of his shrieking laughter

2) to pull him out of the job and to encourage him to pursue
higher endeavors.
