a number mystery

Quite a while ago, Ray's teacher Miss. Betty told us Ray impressed her with counting number up to 20, though Ray forgot one or two numbers. That was a pretty good math development. But Ray always forgot number 13. No problem from 1 to 12, then jump to 14, a little shaky after 14 but the only number he consistently missed was 13.
This really puzzled dad. What is wrong with 13? Dad didn't send Ray to Catholic school. Is it the pronunciation?
Dad printed down the numbers up to 100. Guess what? Ray could go up to 100. But he still needs help on 13. Dad googled around but didn't get any answer. What a mystery!
