A Partridge in a Pear Tree

When I was a kid I used to think that the true love in the "12 Days of Christmas" gave him a 'Partragenapare Tree' on the 1st day of Christmas. I guess I just thought it was a strange exotic tree that I'd never heard of before, and as a kid I failed to notice that birds were a common gift of his true love and perhaps I just didn't know what a partridge was at that point in my life. Even now at age 28, I still have a hard time not hearing/singing 'partragenapare tree' instead of "partidge in a pear tree". Perhaps mis-hearing the words to songs is a common thing. My family still can't sing 'He Arose' at church on Easter Sunday without cracking up remembering my little brother's lyrics. Instead of singing, "Up from the grave he arose with a might triumph o'er his foes", my dear brother sang, "Up from the grave he arose with a mighty trumpet for his nose."!
