Three elderly ladies were at the doctor for a cognitive reasoning test. The doctor says to first gal, "What is three times three?"
"297," was her prompt reply.
"Um hmm," says the doctor. The doctor says to the second lady, "It’s your turn now. What is three times three?"
"Friday," she replies.
"Um hmm…" Then the doc says to the third, "Okay, Mam, your turn. What’s three times three?"
"Nine," says she.
"That’s wonderful!" says the doctor. "Tell me, now did you get that answer?"
"Simple," she says, beaming… " I just subtracted 297 from Friday!"
