The Director of a mental institution was trying to make room for pending patients, so he was interviewing current patients to determine if they were fit for dismissal.
Three gents were brought in and seated in his office. He asked the 1st, "What is 3 times 3?" The man answered, "124!"
He asked the 2nd the same question, and the man blurted, "Saturday!"
When the 3rd fellow was asked the question, he calmly replied, "Nine."
Thrilled, the director informed patient #3 that he was cured and eligible for immediate release. His curiosity got the best of him, so he asked how the patient derived the answer so quickly.
"Oh hell" said the patient, "It's simple. I just took 124 and subtracted Saturday."
