If Mikey wrote Christmas songs

There's something with dads--my dad does it, Mikey's dad does it--where they like to make up their own words to songs. Well, Mikey must be ripening for fatherhood because almost daily he comes up with new songs to sing to our little girl. It started a few months ago with "Baby Beluga in the deep blue sea" (or Baby Ada in Mommy's belly, You kick so hard, and you're not yet smelly...) But in light of the holiday season, he seems to have taken up Christmas songs. Like this one (sung to "Santa Baby")

Ada baby, you wiggle in Mom's tummy all day--you play

You're an awful good girl, Ada baby,

So hurry down the birth canal tonight.

I'm not so sure about using the words "birth canal" in any sort of song...He may have to rethink this one...
