three

A man and a woman had a little baby
Yes they did,
There were three in the family
That's the magic number

I've been humming this part of the song to myself for months now (along with 'Wiggly Woo', which I've sung to our littleoneint'oven every night since s/he started reacting to soundy things), so I'm chuffed to be able to tie it in with today:

Happy 3rd Birthday, Blip. From Me, Lady Sp33d and the Sp33d Bump :)
