Oh, the number one is not my favorite number (why?) 'Cause one means only me and there's no you (aw, Ernie) But one plus one you see Makes two, that's you and me And it's more fun when one and one make two Oh, one and one make two At least I'm pretty sure they do Oh yes it's true One and one make two Now, say you want to play upon a seesaw You're all alone and don't know what to do (well, what would I do, Ernie?) Well, just go and find a friend And he'll sit on the other end You'll have more fun when one and one make two Oh, one and one make two At least I'm pretty sure they do Oh yes it's true One and one make two Now, everyone needs somebody to share with A pal to help and care for through and through And there's no one that I've known Who can do those things alone It's a lot nicer when one and one make two Oh, one and one make two At least I'm pretty sure they do Oh yes it's true One and one make two (Let's sing harmony!) One and one make two At least I'm pretty sure they do Oh yes it's true One and one make two I said, it's true One and one make two They certainly do One and one make two-oo-ooh!
