a curl in the middle of his forehead

Pa (my grandpa) used to tell me this little rhyme:

There was a little girl
who had a little curl,
right in the middle of her forehead.
When she was good
she was very, very good;
but when she was bad she was - and I'd interrupt and say "Pa, don't say that word."

(The word was horrid.)

Well if you have a look at the pictures Drew posted March 24, I think you'll see that Sam has his own little curl right in the middle of his forehead. The rhyme held true for me. I wonder if Sam will either be very, very good or ... well, you know.
