Girl: Hey, hey, America, can you sing me "We Wish You a Merry Christmas" as my early Christmas present?

Me: Sure!

Me: We wish you a Merry Christmas, we wish you a Merry Christmas, we wish you a Merry Christmas, and a Happy New Year!

Good tidings we bring to you and your kin, we wish you a Merry Christmas and a Happy New Year!

Now bring us some figgy burgers, now bring us some figgy burgers-

Girl: *dies of laughter*

Me: Huh? What did I do wrong?
